SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• To install the heater, as well as the gas and elec-
trical supplies, in accordance with applicable
specifications and codes. Roberts-Gordon LLC
recommends the installer contact a Local Building
inspector or Fire Marshal for guidance.
• 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.
• To furnish all needed materials not furnished as
standard equipment.
• Plan location of supports. Locate a support near
all elbows.
• To provide access to burners for servicing on all
sides and for burner removal.
• To provide the owner with a copy of this installa-
tion, operation and service manual.
• To never use heater as support for a ladder or
other access equipment and never hang or sus-
pend anything from heater.
• To ensu re there is adequ
ate air circulation around
the heater and to supply air for combustion, venti-
lation 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).
• To ensure the heater is placed in an approved
application.
• Be sure the heater has a downward pitch of 1/2"
per 20' (1 cm per 6 m) away from the burner.
• A minimum of 10' (3 m) of tubing on HE-60/80 and
a minimum of 15' (4.6 m) of tubing on HE-100/
125/150/175 are required between the burner and
the first elbow.
• Indoor hanging: Provide a suspension with verti-
cal length of chain or swinging rod which has at
least 2" (5 cm) of horizontal travel for each burner
in a straight run. Be sure the suspension system
is sufficiently flexible to accomodate thermal
expansion, which occurs as the system heats up,
See Page 16, Figure 14.
• Outdoor hanging: Chain should not be used when
installing the unit outdoors. Use a suspension
system which minimizes the lateral movement or
swing which might damage reflectors. See Page
17, Figure 15.
•Washbays/car washes: The heater must not be
exposed to the direct spray from a pressure
washer. To reduce the possibility of spray enter-
ing the burner, utilize an outside combu stion air
supply. See Page 40, Section 8.12.
The heater has been extensively tested under
extreme conditions and is highly resistant to the out-
door elements. Care must be taken to design the
proper hanging brackets and suspension (See Page
17, Figure 15) for the heater in high wind areas.
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 com-
bustibles. 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’s con-
trols (e.g. thermostat or ROBERTS GORDON
®
Con-
troller).
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.
Know your model number and installed configuration.
Model number and installed configuration are found
on the burner and in the Installation, Operation and
Service Manual. See Page 7, Figure 3 through Page
10, Figure 12. Write the proper clearance dimensions
in permanent ink according to your model number
and configuration in the open spaces on the tag.
