SAFETY INFORMTION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires and
of your household. Someday when there may not be a minute to
lose, everyone's safety will depend on knowing exactly what to
do. If, after reading the following information, you feel you still
need more information, please contact your gas supplier.
explosions. In its natural state, propane is odorless and colorless.
You may not know all the following safety precautions which can
protect both you and your family from an accident. Read them
carefully now, then review them point by point with the members
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
•
•
Donotoperateelectricswitches,lightmatches,useyourphone.
Do not do anything that could ignite the gas.
Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
•
Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
•
•
Close all gas tank or cylinder supply valves.
•
Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
LP-Gas is heavier than air and may settle in low areas such as
basements. When you have reason to suspect a gas leak, keep
out of basementsand other low areas. Stay out untilfirefighters
declare them to be safe.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
Theodorantinescapedgascanadsorborabsorbontoorintowalls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels.Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
SOME POINTS TO REMEMBER
•
•
•
•
Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it to
find out what the propane odor smells like. If you suspect that
your LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
reinstalled old tanks, if they are filled and allowed to set too
long before refilling. Cylinders and tanks which have been out
ofserviceforatimemaydevelopinternalrustwhichwillcause
odor fade. If such conditions are suspected to exist, a periodic
sniff test of the gas is advisable. If you have any question about
the gas odor, call your LP-gas dealer. A periodic sniff test of
the LP-gas is a good safety measure under any condition.
Ifyouarenotqualified,donotlightpilotlights,performservice,
or make adjustments to appliances on the LP-Gas system. If
you are qualified, consciously think about the odor of LP-Gas
prior to and while lighting pilot lights or performing service
or making adjustments.
•
•
If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
Sometimes a basement or a closed-up house has a musty smell
that can cover up the LP-Gas odor. Do not try to light pilot
lights, perform service, or make adjustments in an area where
the conditions are such that you may not detect the odor if
there has been a leak of LP-Gas.
If you experience a complete "gas out," (the container is under
no vapor pressure), turn the tank valve off immediately. If the
container valve is left on, the container may draw in some air
through openings such as pilot light orifices. If this occurs,
some new internal rusting could occur. If the valve is left
open, then treat the container as a new tank. Always be sure
your container is under vapor pressure by turning it off at the
container before it goes completely empty or having it refilled
before it is completely empty.
Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or

Pressure Testing of the Gas Supply System
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.
2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2
psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping
systembyclosingitsindividualmanualshutoffvalveduringany
pressure testing of the gas supply piping system at test pressures
equal to or less than 1/2 psig (3.5 kPa).
The use of the following gas connectors is recommended:
— ANSZ21.24ApplianceConnectorsofCorrugatedMetalTubing
and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
havingjurisdiction.ThestateofMassachusettsrequiresthataflexible
appliance connector cannot exceed three feet in length.
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the fireplace gas valve, it will
result in a hazardous condition.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5" w.c. (.872kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 5.0" w.c.
(1.245kPa) for the purpose of input adjustment to a maximum of
10.5" w.c. (2.614kPa) Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 11.0" w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of
13.0" w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection, is located on the outlet side of the gas control.

FURNACE INSTALLATION (continued)
Be sure to deburr the ends with a file after cutting. Installation is
the vent system. In doing this, it is important to securely seal the
vent system and slope all horizontal runs downward 1/4" (6mm)
per foot (305mm) toward the vent terminal outside to drain out
any condensate. It is also necessary to adequately support both the
exhaust and intake and to center the exhaust pipe in the wall.
easy after cutting the wall opening secure the vent terminal box
in place using the (4) 10 x 1" hex-head screws provided. Locate
the box so that the middle exhaust tube is directed toward the
furnace exhaust outlet opening. See Figure 8. Attach the black 2"
flexible inlet air hose to the bottom 2" connector on the vent box
using a hose clamp. Secure the other end to the lower inlet air
box connector using the hose clamp. Do not kink hose. Attach the
long straight end of the 2" orange silicone exhaust elbow to the
middle vent terminal tube and rotate the elbow toward the furnace
exhaust outlet. Secure the hose to the vent box using a hose clamp.
Carefully push the furnace back closer to the wall and secure the
exhaust elbow to the 2" exhaust tube exiting the unit. Secure the
elbow in place using the last remaining hose clamp. The furnace
can now be secured to the wall.

Installation of Shroud
To complete inside installation, secure furnace to the wall bracket
by attaching the two wall mounting brackets to the wall bracket
by using (2) 10 x 1/2" (13mm) hex-head screws provided (See
Figures 4 and 6). To attach the right shroud and left shroud to the
casing back, the 3/4" wide flange on the shroud must be positioned
toward the casing side. When positioned correctly, the (6) louvers
on the shroud will be facing up and the knock-out on the shroud
will be facing down. Attach the right shroud and left shroud to the
casingbackwith(3)10x1/2"hex-headscrewssuppliedinhardware
package, for each shroud. Attach top shroud to right shroud and
left shroud with (4) Phillips-head screws, supplied in hardware
package. Insert air filter into top shroud.
The furnace can be vented with up to a maximum length of 15'
(4.6m) including termination vent and using 2 - 90° elbows. Also,
the furnace can be vented with up to a maximum length of 10'
(3m) including termination vent and using 3 - 90° elbows. For
longer vent lengths order the vent kit, Part Number DVE-1 and
DVE-2. See Figures 11 and 12 illustrating extended vent run and
venting options.
Attention:Iftherightshroudandleftshroudareinstalledincorrectly,
with the 3/4" wide flanges facing inward, the top shroud will not
be able to be installed onto the side shrouds. The top shroud will
appear to be 2 inches, too narrow.
Note: If the extended vent kit is used and the exhaust vent pipe
is run through a cold space, such as an attic or a garage, the pipe
should be insulated using 1/2" (13mm) thick fiberglass insulation
or equivalent to keep the flue products warm enough to avoid
condensation. Also, slope 1/4" (6mm) per foot (305mm) the vent
terminal horizontal run downward toward the outside of the house
to assure any condensate flow out of vent system. Horizontal
vent pipe runs of 5 feet (1.5m) or more in length may accumulate
condensation in the exhaust pipe and must, therefore, be sloped
downward to drain any condensate out of the end vent terminal.
Use straps or other suitable supports spaced every 5 feet (1.5m) to
adequately hold pipe. Be sure to avoid any low spots or sags in
pipe run. Be sure all connections are tight using the hose clamps
as shown in Figure 9, "Vent Coupling Connections."
Vent Terminal (Figure 10)
Place the 6 3/8" x 6 3/8" (162mm x 162mm) black foam, wall plate
gasket within the mounting plate. The 4 3/4" (121mm) diameter
hole in the black foam gasket will allow for installation of the
concentricventtubeassembly.Slidetheoutsidemountingplateinto
place on the concentric vent tube assembly. The outside mounting
plate should seal against the face of the building and be secured
in place using (4) 10 x 1" hex-head screws. Be sure to caulk and
seal around the pipe on the exterior using high temperature exterior
grade, silicone caulk rated at 204°C/400°F. Wipe some silicone
sealant on the 2" (51mm) exhaust pipe extension. The end cap can
be pushed into place on the exhaust outlet tube.
For wall depths thicker than 10" (254mm) order the extended vent
terminal kit which will cover walls to 32" (813mm) thickness.
The vent pipes must be cut to length to assemble for desired wall
thickness.
Attention: The opening on the bottom of the end cap must be
positioned toward the ground. The opening on the bottom cannot
be pivoted to the right or left, it must be centered toward the
ground.

Whenever a vertical vent run, in a heated room [10 ft. (3m) or more
for DV-40E or 6 ft. (1.8m) or more for DV-20E] and a horizontal
vent run are combined, you must purchase the optional condensate
drain kit, part number DV-1108. If the vertical vent run lengths are
less than those required for the condensate drain kit, you can slope
the horizontal vent run portion, downward 1/4" (6mm) per foot
(.3m) to the outside. However, if local codes prohibit condensate
from draining outside and the appliance produces condensate, the
horizontal portion of the vent run must slope downward, to the
appliance,1/4"(6mm)perfoot(.3m). Thiswillallowanycondensate
to flow into the condensate drain kit. Do not use the orange silicone
elbow supplied with unit to catch condensate. You can route the
condensate from the condensate drain kit to an existing drain or
into the condensate drain pan located within the appliance.
Whenever a horizontal vent run is used, where local codes allow,
you can slope the exhaust pipe downward, to the outside, 1/4"
(6mm) per foot (305mm). The downward slope on the exhaust
pipe will allow any condensate to flow out of the exhaust pipe. If
local codes prohibit condensate from draining to the outside and
the appliance produces condensate you must purchase condensate
drain kit, part number DV-1108.

Oiling
The blower motor has an oil hole located on each end of the motor.
Use #20 motor oil only. It is best to oil the motor several times
during the heating season using 2 or 3 drops each time.
OPERATION AND TROUBLESHOOTING
Your new furnace should provide many years of trouble free
performance, however, a yearly inspection of the burners , flue
passageways and the outlet vent assembly should be done. Be
sure all passageways are open and clear of any obstruction, or soot
build up. Be sure to shut off all power to the unit while performing
this inspection.
The hot surface ignitor is energized and after a 17 second warm-
up, the gas valve circuit is energized, opening the gas valve
and igniting the burners. After burning for about 30 seconds,
the circulating air blower comes on, delivering warm air to
the room. If ignition does not occur, the ignition sequence is
repeated again up to 2 more times. (3 trials for ignition-total)
3. After the furnace operates and satisfies the thermostat, the gas
valve closes and the circulating air blower continues to run for
about 2 minutes and then shuts off. The inducer blower runs
for 5 seconds and shuts off.
Periodically remove the circulating air filter and clean with water
to remove all dirt. Shake dry and reinstall in unit.
System Operation
1. This furnace has an electronic thermostat and control board
to monitor the room temperature and then control the furnace
operation to provide the best comfort and performance from a
heating appliance. To operate unit turn ON/OFF switch to ON
and then turn temperature control knob clockwise slowly till
furnace turns on. For typical room comfort, the control knob
should be pointed toward medium.
2. The furnace control board follows sequence of operation which
allows for self diagnosis in the event there is a problem. The
control then blinks a status light, a set number of blinks based
on what problem has been encountered. When the furnace is
on and there is a no fault condition, the green LED is on.
On a typical call for heat by the integral thermostat 24 VAC is
applied to the W terminal on the board.
If for any reason ignition and operation does not occur, the
control board will blink the green fault status LED, a sequence
code, indicating what to look for as a troubleshooting guide.
If the green LED is ON but not blinking check the electronic
temperaturecontroltoverifyitsoperation.Thiscanbeeasilydone
bydisconnectingthe3electronictemperaturecontrolleadsfrom
the main furnace board and using a pig tail jumper to connect
R & W together on the board. If the furnace comes on and runs
normally the temperature control board is malfunctioning. If
the heater still does not come on, then the main furnace board
is malfunctioning. Look for any fault codes below and verify
the 3 amp fuse is not blown.
The inducer blower circuit is energized and the inducer blower
comes on for 15 seconds pre-purging out any gas and closing
the pressure switch.
