CLEARANCE TO COMBUSTIBLES
A general clearance of 18” (46 cm) in every direction is recommended for servicing.
In addition to this it is very important to observe the minimum clearance to combustibles at all times to
avoid any possibility of property damage or personal injury.
WARNING
Clearances as marked on the heater body must be maintained from vehicles parked beneath. Signs should be
posted identifying any possible violation of the clearance distances from the heater in all vehicle areas.
Maximum allowable stacking height in storage areas should be identified with signs or appropriate markings
adjacent to the thermostat or in a conspicuous location.
Clearance to combustibles DO NOT indicate acceptable distances from PVC paneling. Refer to panel
manufacturers recommendations.
Combustible materials are considered to be wood, compressed paper, plant fibres, plastics, Plexiglas or other
materials capable of being ignited and burned. Such materials shall be considered combustible even though flame-
proofed, fire-retardant treated or plastered.
Adequate clearance to sprinkler heads must be maintained (
NFPA 13: Standard for the Installation of Sprinkler
Systems)
.
The stated clearance to combustibles represents a surface temperature of 90°F (32°C) above room temperature.
It is the installer’s responsibility to ensure that adjacent materials are protected from deterioration.

VENTING & COMBUSTION AIR
General Requirements
Refer to the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) in the US and CSA B149.1 Installation Code
in Canada, as well as all local requirements for general venting guidance.
Heaters may be installed vented or unvented.
Heaters may be vented horizontally or vertically.
Optional outside air supply may be directed to the heater.
Polypropylene vent system
The heater has been approved for a venting system, which uses single wall, rigid, Polypropylene pipe
system approved for sustained flue gases up to 230°F (110°C).
Venting system must be installed by following the vent manufacturer’s instructions.
Installations must comply with applicable national, state, and local codes. For Canadian installation,
Polypropylene vent must be listed as a ULC-S636 approved system.
DO NOT mix vent systems of different types or manufacturers. Failure to comply could result in severe
personal injury, death, or substantial property damage.
IMPORTANT
-Maximum total exhaust vent length allowed for this heater: 4” (110 mm) venting 12’ (3.7 m) and 6”
(160 mm) venting 25’(7.6 m), plus up to two 87° elbows and vent terminal (45° elbow with bird
screen).
-Maximum total fresh air inlet duct length allowed for this heater: 4” (110 mm) venting 12’ (3.7 m)
and 6” (160 mm) venting 25’ (7.6 m), plus up to two 87° elbows and air inlet terminal (45° elbow
with bird screen).
-Total of vent length plus outside air supply duct length cannot exceed 25’ (7.6m) on 4” (110 mm)
venting and 50’ (15.2 m) on 6” (160 mm) venting.
Note: The above stated requirements assume a maximum of 2 elbows in the total combination of vent
and air supply duct. Subtract 5’ (1.5 m) of allowable length for each elbow if 3 or more elbows are
used.
-Install a minimum 18” (46 cm) straight length of duct for air intake or vent before any Tee or elbow.
-Do not install any elbow or 45° fitting to bring vent lower than the horizontal tube system.
-Consult factory for use of common venting.
-Follow the vent pipe manufacturer's instructions and the instructions in this manual when installing the
vent pipe.

Series THE Page 12 LT194 Feb 2017
General rules for vent terminals
Be not less than 7’ (2.1 m) above grade when located adjacent to public walkways.
Terminate at least 3’ (0.9 m) above any forced air inlet located within 10’ (3 m).
Terminate at least 4’ (120 cm) below, 4’ (120 cm) horizontally from or 1’ (30 cm) above any door, window, or
gravity inlet into any building.
Be located at least 12” (30 cm) from any opening through which vent gases could enter a building.
Extend beyond any combustible overhang.
Be installed at a height sufficient to prevent blockage by snow.
Vent terminal(s) and/or intake air must be a minimum of 24” (60 cm) above any parapet, vertical wall or
structure within 10’ (3 m) horizontally.
Note: In cold climates water vapor in the exhaust gases will condense into a cloud of vapor where the vent exits the
building. Extending the exposed vent piping up to a maximum of 6” (15 cm) from the wall helps vapor from being
trapped along a building’s face.
Condensation management
Heater develops some condensation in the vent piping. When using long runs of venting or when the venting
passes through cold or unheated areas, considerable amounts of condensate from the flue gases can develop.
Condensate should drain freely from the vent system and should collect in a siphon that can be drained. A 4"
(110 mm) Flanged Drain Adaptor is supplied with heater. A siphon should be installed in the drain nipple. Fill
the siphon with water before appliance start-up.
The vent should slope towards the heater and condensate collector.
Damage to heat exchanger and pipe vent may occur if the condensate is allowed to collect and freeze. Pooling
of condensate can restrict airflow and can cause nuisance failures of the system.
Condensate is corrosive and should be treated and disposed of according to local codes.
If condensation in the outside air supply duct is a problem, shorten or adequately insulate the section.
Un-Vented Operation
Requirements for combustion air supply and dilution air vary by jurisdiction, building type and specific
installation details. See local codes for guidance. In general, fresh air ventilation must be provided to the
building space at 4 cfm per 1000BTU/Hr in USA (3 cfm per 1000 BTU/Hr in Canada).
Optional outside air supply is not recommended for unvented heaters due to possible pressure imbalances in
the building space.
Ensure that minimum combustible clearances are maintained for unvented heaters. Refer to Table 2, for
required clearance dimensions.
Combustion Air Supply (Optional)
An outside combustion air supply is strongly recommended if the building space encloses a negative pressure
due to exhaust etc. or if the building contains materials which would expose the heater to halogenated
hydrocarbon atmospheres.
The outside air terminal should be located at an elevation equal to or below the vent terminal elevation to
prevent back-venting of flue gases into the burner compartment.
Install single wall pipe PP or PVC pipe.
If installing both an intake air and vent terminal through a sidewall there must be a minimum of 36” (90 cm)
separation, measured on vertical center line, between the intake air and vent terminations.

GAS PIPING
The gas meter and service must be sufficiently large to supply gas to the connected building gas load
including the heating equipment and any other gas fired equipment. Additionally, the gas distribution piping
must be designed according to local and national ordinances. Generally (low pressure) systems designed
with a maximum ½" W.C. total pressure drop meet this requirement.
Gas supply pipe sizing must be in accordance with the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) in
the US and CSA B149.1 Installation Code in Canada.
Before connecting burners to the gas supply system, verify that high pressure testing of the system has been
completed. Failure to do so may expose the burner components to damaging high pressure, requiring
replacement of key components.
In USA, use a flexible metal connector certified to ANSI Z21.24/CSA 6.10 Standard for Connectors for Gas
Appliances at lease ½-in dia; 24-in to 36-in in length.
In Canada, a radiant tube type infrared heater shall be connected with a Type I hose connector certified to
CAN/CGA 8.1 Standard for Elastomeric composite Hose and Hose Couplings for Conducting Propane and
Natural Gas of a length of 36-in ± 6-in (90 ± 15 cm).
Flexible gas connectors of approved type must be installed as shown in Figure 10, in one plane, and without
sharp bends, kinks or twists. A smooth loop of approximately 12” (30 cm) in diameter is best. Failure to install the
gas connection in the approved manner will result in a hazardous and potentially deadly situation due to the
movement of the heat exchanger and burner in the normal course of operation
Figure 10: Flexible Gas Connections
ELECTRICAL WIRING
Wiring diagram
The heater is normally controlled by low voltage (24V) thermostats. In all cases, the heater must be grounded in
accordance with the National Electric Code, ANSI/NFPA 70 in the US, and the Canadian Electric Code, CSA C22.1
in Canada, and must comply with all local requirements. The heater may also be controlled with a manual line
switch or timer switch in place of the thermostat. Refer to Figure 11 for guidance on electrical wiring of heaters.
If any of the original wire as supplied with the heater must be replaced, it must be replaced with wiring having a
rating of at least 105°C temperature service and 600 volts capability.

Series THE Page 16 LT194 Feb 2017
Figure 11: Wiring Diagram using 24VAC Thermostat
High Limit Controls
Heat Exchanger High Limit Switch
This device is located on the heat exchanger box and limits the maximum temperature of the heat exchanger. If the
flue gas temperature rises above the temperature setting, the switch opens causing the heater to shut down. The
switch will auto reset once the temperature drops sufficiently.
Blower Air Pressure Switches
The blower/heater is equipped with an air pressure switch located in the burner box. This device is connected in
series with heat exchanger high limit switch and monitors the air pressure produced by the blowers. In the event
that the exhaust venting or the intake pipe becomes blocked or sufficiently restricted, the normally open air
pressure switch will shut down the heater.

BURNER OPERATION
Starting sequence of operation
Turn the thermostat up. When the thermostat calls for heat, both blower motors will energize.
After blowers running, the air-proving switch closes and activates the ignition module.
The ignition module, after a pre-purge period of approximately 30 seconds, energizes the igniter.
Additionally, the gas valve is energized for this ignition trial period of 15 seconds.
If a flame is detected, the ignition sensing rod "reads" a rectification signal and the gas valve remains
open. The sparking stops when the flame signal is established.
If no flame is detected, the gas valve closes and a 30 seconds inter-purge period begins.
After the inter-purge, the module repeats the trial for ignition period.
If flame is still not established, a third and final inter-purge followed by a final ignition trial cycle begins. After
three trials, the module will lockout for a period of approximately 1 hour or until reset. (Reset is accomplished
by removing power from the module for at least 5 seconds.) After this 1 hour period, the module re-attempts
the full ignition sequence.
Note: When using a 24V thermostat and the heat requirement has been met and the thermostat opens,
the burner shuts off but the blowers continue to run for approximately 30 seconds. This is referred to as
a post purge. This allows the products of combustion to be removed from the heat exchanger to avoid
nuisance condensation and increase heat exchanger life.
Maintenance
For best performance, the certain minimal maintenance procedures should be performed before each heating
season:
Installation environment and best practices should be considered in determining frequency.
Before performing any services or maintenance, shut off gas and electrical supply to heater.
Check condition of heat exchanger forced air blower. Dirt and dust may be blown or vacuumed from the
blower.
Check condition of heat exchanger. Dirt and dust may be blown or vacuumed from the heat exchanger core /
box.
Check condition of burner box blower by removing the flex duct. Dirt and dust may be blown or vacuumed
from the blower.
Check condition of burner. Remove any foreign objects or debris from inside the burner box or burner cup.
Inspect the igniter. Replace igniter if there is excessive wear or erosion, breakage or other defects.
Be sure the burner observation window is clean and free of cracks or holes. Clean or replace as necessary.
Check the flue pipe for soot or dirt and reattach to the heater after cleaning as necessary.
The reflector sections may be cleaned by wiping with a damp cloth.
A service agency qualified to adjust and repair infrared heaters should be engaged for service other than
routine maintenance.
Be sure vent terminal and fresh air inlet are free from obstructions. If either pipe is restricted, the safety air
switch will not operate properly, and the heater could fail to operate.
Check the inside of the radiant tubes visually with a flashlight. If carbon or scale are present, scrape or
otherwise remove deposits (a wire brush works well)
