BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL
SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
permanent ink according to your model number and
configuration in the open spaces on the tag.
2.2 Corrosive Chemicals
• To install the heater, as well as the gas and
electrical supplies, in accordance with applicable
specifications and codes. Roberts-Gordon LLC
recommends the installer contact a local Building
Inspector or Fire Marshal for guidance.
CAUTION
• To use the information given in a layout drawing
and in the manual together with the cited codes
and regulations to perform the installation.
• To install the heater in accordance with the
clearances to combustibles.
Product Damage Hazard
Do not use heater in area containing
corrosive chemicals.
• To furnish all needed materials not furnished as
standard equipment.
Refer to appropriate Material Safety Data
Sheets (MSDS).
• To plan location of supports.
• To provide access on all sides for burner servicing
and removal.
Failure to follow these instructions can result
in product damage.
• To provide the owner with a copy of this
Installation, Operation and Service Manual.
Roberts-Gordon LLC cannot be responsible for
ensuring that all appropriate safety measures are
undertaken prior to installation; this is entirely the
responsibility of the installer. It is essential that the
contractor, the sub-contractor, or the owner identifies
the presence of combustible materials, corrosive
chemicals or halogenated hydrocarbons* anywhere
in the premises.
• To never use heater as a support for a ladder or
other access equipment and never hang or
suspend anything from heater.
• To ensure there is adequate air circulation around
the heater and to supply air for combustion,
ventilation and distribution in accordance with
local codes.
• To safely and adequately install heater using
materials with a minimal working load of 75 lbs
(33 kg).
* Halogenated Hydrocarbons are a family of
chemical compounds characterized by the
presence of halogen elements (fluorine, chlorine,
bromine, etc.). These compounds are frequently
used in refrigerants, cleaning agents, solvents, etc.
If these compounds enter the air supply of the
burner, the life span of the heater components will
be greatly reduced. An outside air supply must be
provided to the burners whenever the presence of
these compounds is suspected. Warranty will be
invalid if the heater is exposed to halogenated
hydrocarbons.
• To ensure the heater is placed in an approved
application.
2.1 Wall Tag
A laminated wall tag is available for the heater as
a permanent reminder of the safety instructions and
the importance of the required clearances to
combustibles. Please contact Roberts-Gordon LLC
®
or your ROBERTS GORDON independent
distributor to obtain the wall tag. Affix the tag by
peeling off the backing of the adhesive strips on the
rear surface and position the tag on a wall near the
heater (e.g. thermostat or ROBERTS GORDON
Controller).
A copy of the wall tag (P/N 91037912) is illustrated on
the back cover. For an immediate solution, you may
affix this copy on the wall near the heater.
2.3 National Standards and Applicable Codes
All appliances must be installed in accordance with
the latest revision of the applicable standards and
national codes. This refers also to the electric, gas
and venting installation. Note: Additional standards
for installations in public garages, aircraft hangars,
etc. may be applicable.
®
Know your model number and installed configuration.

SECTION 3: CLEARANCES TO COMBUSTIBLES
SECTION 3: CLEARANCES TO COMBUSTIBLES
WARNING
3.1 Required Clearances to Combustibles
Clearances are the required distances that
combustible objects must be away from the heater to
prevent serious fire hazards. Combustibles are
materials that may catch on fire and include common
items such as wood, paper, rubber, fabric, etc.
Maintain clearances to combustibles at all times
for safety.
Fire Hazard
Clearances for all heater models are located on the
clearances on each burner for the model heater
being installed to make sure the product is suitable
for your application and the clearances are
maintained. Read and follow the safety guidelines
below:
Keep all flammable objects, liquids and
vapors the minimum required clearances to
combustibles away from heater.
Some objects will catch fire or explode when
placed close to heater.
Failure to follow these instructions can result
in death, injury or property damage.
• Keep gasoline or other combustible materials
including flammable objects, liquids, dust or
vapors away from this heater or any other
appliance.
• If the radiant tubes must pass through the building
structure, be sure that adequate sleeving and fire
stop is installed to prevent scorching and/or fire
hazard.
• The stated clearances to combustibles represents
a surface temperature of 90° F (50° C) above
room temperature. Building materials with a low
heat tolerance (such as plastics, vinyl siding,
canvas, tri-ply, etc) may be subject to degradation
at lower temperatures. It is the installer’s
responsibility to assure that adjacent materials
are protected from degradation.
• Maintain clearances from heat sensitive
equipment and workstations.
• Maintain clearances from vehicles parked below
the heater.
• Maintain clearances from swinging and overhead
doors, overhead cranes, vehicle lifts, partitions,
storage racks, hoists, building construction, etc.
• In locations used for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to maintain
required clearances from the heater to the
combustibles. Signs must be posted adjacent to
the heater thermostat. In the absence of a
thermostat, signs must be posted in a
conspicuous location.
• Consult local Fire Marshal, Fire Insurance Carrier
or other authorities for approval of proposed
installation when there is a possibility of exposure
to combustible airborne materials or vapors.
• Hang heater in accordance to the minimum

SECTION 9: GAS PIPING
SECTION 9: GAS PIPING
The gas hose accommodates expansion of the
heating system and allows for easy installation and
service of the burner. Before connecting the burners
to the supply system, verify that all high pressure
testing of the gas piping has been completed.
There is an expansion of the tube with each firing
cycle; this will cause the burner to move with respect
to the gas hose. This can cause a gas leak resulting
in an unsafe condition if the gas connection is not
42.
WARNING
Fire Hazard
Tighten gas hose fittings to connect gas
supply according to Figure 23.
Meter and service must be large enough to handle all
the burners being installed plus any other connected
load. The gas hose which feeds the system must be
large enough to supply the required gas with a
maximum pressure drop of 1/2" w.c. When gas piping
is not included in the layout drawing, the local gas
supplier will usually help in planning the gas piping.
Gas hose can crack when twisted.
Gas hose moves during normal operation.
Use only 36" (91 cm) long connector of 1/2" or
3/4" nominal ID.
Connector supplied with heater for U.S.
models (not with Canadian models).
Gas lines must meet applicable codes:
United States: The Flexible Stainless Steel Gas
Hose (US models) supplied with the heater is certi-
fied per the Standard for Connectors for Gas Appli-
ances, ANSI Z21.24/CSA 6.10 - latest revision.
Canada: The Rubber Type 1 Gas Hose (Canadian
models) optional with the heater is certified as being
in compliance with the Standard for Elastomeric
Composite Hose and Hose Couplings for Conducting
Propane and Natural Gas, CAN/CGA 8.1 - Latest
revision.
Failure to follow these instructions can result
in death, injury or property damage.
WARNING
• Check the pipe and tubing ends for leaks
before placing heating equipment into
service. When checking for gas leaks, use a
soap and water solution; never use an open
flame.
Explosion Hazard
Leak test all components of gas piping
before operation.
Gas can leak if piping is not installed
properly.
Do not high pressure test gas piping with
heater connected.
Failure to follow these instructions can result
in death, injury or property damage.
