HE-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL
SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• 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.
• 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 installation, 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 ensure 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 combustion 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 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’s controls (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, Fi g ure 1 2 . Write the proper clearance dimensions
in permanent ink according to your model number
and configuration in the open spaces on the tag.

2.2 Corrosive Chemicals
CAUTION
Product Damage Hazard
Do not use heater in area containing
corrosive chemicals.
Refer to appropriate Material Safety Data
Sheets (MSDS).
Failure to follow these instructions can result
in product damage.
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.
SECTION 2: INSTALLER R ESPONSIBILITY
* 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.
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.

HE-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL
WARNING
Fire Hazard
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.
SECTION 3: CLEARANCES TO COMBUSTIBLES
3.1 Required Clearances to Combustibles
Clearances are the required distances that combusti-
ble 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 clear-
ances to combustibles at all times for safety.
• 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 sus-
pension requirements on Page 16, Figure 14.
• If the radiant tubes must pass through the building
structure, be s
stop is installed to prevent scorching and/or fire
hazard.
ure that adequate sleeving and fire
Clearances for all heater models are located on the
burner of the heater and on Page 7, Figure 3 through
Page 10, Figure 12 in this manual. Check the clear-
ances 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 gasoline or other combustible materials
including flammable objects, liquids, dust or
vapors away from this heater or any other appli-
ance.
• 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, triply, 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.

2. The overlap at the first and second reflector is a slip overlap.
Thereafter, every third reflector joint is a slip overlap. A slip
overlap is achieved by either:
a.) both reflectors lay inside a hanger.
(No reflector support needed.)
b.) using a reflector support with
loose screws at the reflector
overlap.
3. The remaining reflector overlaps require a non-slip
overlap connection. To affix the reflectors together in
a non-slip overlap either:
a.) use reflector support and tight screws.
b.) if both reflectors lay inside a hanger, u-clips or
sheet metal screws may be used.
This section of three reflectors joined together must
be affixed to the tube with at least one reflector support
with tight screws.

Step 6.6.1 Reflector, U-Clip and Reflector Support Installation
The pictorial drawings of the heater construction in
Section 6 are schematic only and provide a general
guideline of where hangers, reflector supports and Uclips are to be installed.
To ensure proper expansion and contraction move-
ment of the reflectors, a combination of U-clips and
tor supports and U-clips depends on the individual
installation. Use either pop rivets or sheet metal
screws instead of u-clips when installing end caps
and joint pieces in areas where impact and high wind
may be a factor. The following rules must be
observed.

This heater must be vented in accordance with the
rules contained in this manual and with the following
national codes and any state, provincial or local
codes which may apply:
United States: Refer to National Fuel Gas Code
NFPA 54/ANSI Z223.1 - latest revision.
Canada: Refer to Natural Gas and Propane
Installation Code CSA B149.1 - latest revision.
Exhaust end of heater will accept a 4'' (10 cm) vent
pipe using the vent adapter (P/N 90502700). To
prevent leakage of condensation, install the vent
adapter with the seam on top and seal the joint using
a high temperature silicone sealant.
All vent joints should be sealed using suitable
product such as General Electric RTV106 or
Permatex Form-a-Gasket red high temperature
silicone adhesive sealant.
Vent pipe must be sloped downward away from the
burner 1/2'' (1 cm) for every 20' (6 m).
The heater may be individually vented or common
vented. When venting horizontally, a maximum of two
heaters can be commonly vented. See Page 39,
Section 8.10. When venting vertically, a maximum of
four heaters can be commonly vented. See Page 40,
Section 8.11.
The heater may also be installed unvented in certain
circumstances according to building ventilation
codes. Refer to the above codes and Page 36,
Section 8.2 for further information. Unvented
operation also requires compliance w
clearances to combustibles given on Page 10, Figure
12.
The bottom of the vent or air intake terminal shall not
be located less than 1' (.3 m) above grade level.
The vent shall not terminate less than 7' (2.1 m)
above grade where located adjacent to public
walkways.

8.1.1 United States Requirements
Vent must terminate at least 3' (.9 m) above any
forced air inlet located within 10' (3.1 m).
Vent must terminate at least 4' (1.2 m) below, 4'
(1.2 m) horizontally from, or 1' (.3 m) above any door,
operable window, or gravity air inlet into any building.
8.1.2 Canadian Requirements
The vent shall not terminate within 6' (1.8 m) of a
mechanical air supply inlet to any building.
The vent shall not terminate within 3' (.9 m) of a
window or door that can be opened in any building,
any non-mechanical air supply inlet to any building,
or of the combustion air inlet of any other appliance.
8.2 Unvented Operation
Sufficient ventilation must be provided in the amount
of 4 cfm per 1000 Btu/h firing rate (United States); 3
cfm per 1000 Btu/h firing rate (Canada).
Use of optional outside combustion air is not
recommended with unvented heaters.
If exhaust fans are used to supply
ventilation air, an
interlock switch must be used to prevent the heater
from coming on when the fans are off. This may be
done using a pressure switch.
FIGURE 22: Tube Termination
8.6 Length Requirements
The maximum vent length allowed is 45' (13.7 m).
The maximum outside air supply duct length allowed
is 45' (13.7 m).
The total vent length, plus outside air duct length,
plus any extensions to minimum heat exchanger
lengths, cannot exceed 65' (19.8 m).
Vent length should be limited to less than 20' (6 m). If
using vent lengths greater than 20' (6 m),
condensation will form in the vent pipe. Insulation
and additional sealing measures (high temperature
silicone at all seams) are required. Optional heat
exchanger beyond minimum lengths is considered as
vent length for length determination.
Subtract 15' (4.6 m) of maximum allowed vent or duct
length per vent elbow if more than two are used.
8.3 Horizontal Venting
In noncombustible walls only, vent terminal
(P/N 02537801-1P) may be used.

12.1 Honeywell SmartValve
®
II Troubleshooting
This heater is supplied with the Honeywell Smart-
®
Valve
II control system. This system is equipped with
a diagnostic function that will assist in performing
troubleshooting. The LED (Light Emitting Diode) indicator at the top of the SmartValve
®
II control will flash
in various patterns to indicate status. The LED status
indication chart provided below gives a summary of
possible faults.
LED Status Indicates
Off No power to the control
Bright-Dim Normal Operation.This indication
shows whenever the system is pow-
ered, unless some abnormal event
has occurred.
2 Flashes Pressure switch remains closed lon-
ger than 30 seconds after a call for
heat begins (pressure switch stuck
closed). The SmartValve
®
II checks
the status of the pressure switch contacts and must see a change in the
contact with every firing cycle. Placing
a jumper at the switch out of
sequence will result in a fault, with the
LED indicator flashing 2 times.
3 Flashes Pressure switch remains open longer
than 30 seconds after combustion air
blower is energized. Check for correct
blower operation, blower intake
obstructions, pressure switch tubing
and wiring.
4 Flashes Limit string open, 2" white jumper wire
on valve is loose.
5 Flashes Flame signal sensed out of proper
sequence.
6 Flashes System Lockout. Flame sensing cir-
cuit is not functioning properly. Perform the checks following the "Does
the burner stay lit?" bubble in the trou-
bleshooting flow
chart on Page 54,
Section 12.2.
Page 56, Section 12.3 will provide the information
needed to test the manifold gas pressure setting.
Page 54, Section 12.2 will guide you through several
troubleshooting steps to determine possible problems with the systems.
