CONNECTING
TO GAS
NOTICE
A qualified service person must connect heater to gas supply.
Follow all local codes.
SUPPLY
!
CAUTION
WARNING ICON
G
001
Never connect heater directly to the propane supply. This heater
requires an external regulator (not supplied). Install the external
regulator between the heater and propane supply.
The installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure between 11 and 14
inches of water. If you do not reduce incoming gas pressure, heater regulator
damage could occur. Install external regulator with the vent pointing down as
shown in Figure 10. Pointing the vent down protects it from freezing rain or sleet.

CAUTION
WARNING ICON
G
001
Use only new, black iron or steel pipe. Copper tubing may be used
in certain areas. Check your local codes. Use pipe 3/8" diameter or
greater to allow proper gas volume to heater. If pipe is too small,
undue loss of pressure will occur.
Installation must include a manual shutoff valve, ground joint union, and plugged
1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must
be upstream from heater (see Figure 11, page 10).
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe could result in clogged heater valves.
!
CAUTION
WARNING ICON
G
001
Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown in Figure 11. Locate sediment trap
where it is within reach for cleaning. Locate sediment trap where trapped matter is
not likely to freeze. A sediment trap traps moisture and contaminants. This keeps
them from going into heater controls. If sediment trap is not installed or is installed
wrong, heater may not run properly.

WARRANTY INFORMATION
KEEP THIS WARRANTY
Model
Serial No.
Date Purchased
Always specify model and serial numbers when communicating with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard
written warranty. We make no other warranty, expressed or implied.
LIMITED WARRANTY
COMFORT GLOW VENT-FREE RESIDENTIAL GAS HEATERS
DESA International warrants this product to be free from defects in materials and components for one (1) year from the date
of first purchase, provided that the product has been properly installed, operated and maintained in accordance with all
applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled check must be presented.
This warranty is extended only to the original retail purchaser. This warranty covers only the cost of part(s) required to restore
this heater to proper operating condition. Warranty part(s) MUST be obtained through authorized dealers of this product and/
or DESA International who will provide original factory replacement parts. Failure to use original factory replacement parts
voids this warranty. The heater MUST be installed by a qualified installer in accordance with all local codes and instructions
furnished with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or
become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation.
Travel, diagnostic cost, labor, transportation and any and all such other costs related to repairing a defective heater will be
the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE
PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND
LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MER-
CHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO ONE (1) YEAR FROM THE DATE OF FIRST
PURCHASE; AND DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF
THE PRODUCT AND DESA INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSO-
EVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or
consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply
to you.
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
