WARNING!
Incorrect or improper wiring may result in shock, injury or death. Field wiring to the heater must be
connected and grounded in accordance with national, provincial, local codes and to the guidelines
in this manual. Refer to the most current revisions to the CAN/CSA B149.1 and 2.
2.0 Installation • Electrical Requirements
NOTICE
Radiant heat may damage the flexible power cord. Always keep the flexible power cord away from the heater. Do not allow
the power cord to be subjected to radiant heat.
Control systems are initilized by either 120V or optional 24V control voltage. A 120V system can be operated directly
with 120V to the heater. Heaters with the optional relay can be controlled with 24V.
Transformers (sold seperately) must be used to supply power of sufcient VA rating for single or multiple connected
installations.
Important! Proper grounding and polarity are essential. If the system is not properly grounded, it cannot determine
the presence of a ame and will lockout and shut off.
For wiring of controls see Figure 2.7 below. It is recommended that the control be installed on the hot side of a fused
supply line and have a sufcient ampere capacity rating for the heater(s) it will control (see Figures 3.1 & 3.2).

WARNING!
Ventilation
2.0 Installation • Ventilation
Improper or insufcient ventilation may result in explosion, re, health problems,
carbon monoxide poisoning or death. Vent enclosed spaces and buildings according
to national, provincial and local codes.
The infra-red heater must be vented in accordance with national, provincial and local codes and the guidelines in the
Brant Radiant Heaters PH Series manual. Refer to the lastest edition of the CAN/CSA B149.1 and 2.
It is required that the upper levels of the space to be heated are properly ventilated to supply combustion air to the
heaters and to sufciently dilute the products of combustion. It is also important to keep the ue discharge area clear
of gas piping and electrical wiring (see Figure 2.6).
Provisions must also be made to provide sufcient fresh air intake area and exhaust air outlet area. Natural or
mechanical means shall be provided to supply and exhaust at least 4.0 C.F.M. per 1000 BTU/H of natural gas input,
4.5 C.F.M per 1000 BTY/H of L.P. gas input. Exhaust openings for the removal of ue products must be above the
level of the heater(s).
When insufcient air movement exists, induced air displacement is required. A balanced system is essential to avoid
negative building pressure which causes excessive inltration, unfavorable drafts and affects combustion efciency.
Air displacement may be accomplished by either gravity or mechanical means. Mechanical exhausters are preferred
and typically mounted at high points in the ceiling over where stagnant air accumulates inside. For a at roof,
considerations of prevailing winds, high and low pressure areas, and distribution of air movement must be taken into
consideration when locating exhausters.
Best air distribution is accomplished by using a number of small exhausters versus one large exhauster. Provide a
minimum of one square inch of inlet area per 1000 BTU/H for combustion air supply. Inlet openings in the building
should be well distributed, located high on the wall and should direct incoming air upward to dilute products of
combustion while preventing drafts at lower levels. Inlets are typically 1 to 3 sq. ft.
In certain applications, local codes may require that mechanical exhaust systems be interlocked with the heater(s) to
enable both to function simultaneously or allow control of exhausters with a ceiling mounted humidistat.

Sequence of Operation:
Starting Circuit:
When voltage is applied to L1 and L2, a circuit is completed from L1 via the blower motor to L2. The blower fan
is mounted in the control box and rated to supply sufcient air for combustion. Air pressure generated by the
blower fan will cause the normally open pressure switch to close. Another circuit is completed from L1 to the spark
ignition module and back to L2. After a seven (7) second pre-purge, the spark electrode and gas valve energize
simultaneously. The trial for ignition is fteen seconds.
Running Circuit
After ignition, the ame rod monitors the ame. As long as a ame is present, the valve is held open. If the ame is
lost, the control acts to close the valve within seconds, and a new trial sequence identical to that at start-up is initiated.
If proof of ame is not established within the 15 second trial for ignition, the unit will retry two additional times before
entering lockout mode. If lockout occurs, the control can be reset by briey interrupting the power source.

Always wear clothing that protects the body and use protective glasses when
maintaining the heater.
Electrical shock or explosion may occur when conducting maintenance while the
heater is connected to the power source and gas supply. Disconnect power and gas
supply to heater before servicing.
Burner malfunction may result in explosion or re. Never operate the heater if there
are any signs of malfunction, excessive wear or damage. Call a professional for
assistance.
4.0 Maintenance
WARNING!
4.0 Maintenance
Before each use:
• Check the gas supply line and hose assembly for any possible gas leaks or damage.
• Check heater elements for debris. Visually check burner ames.
• Keep the heated area clear and free of combustible materials, gasoline and ammable vapours and
liquids. Ensure there is no obstruction of the ow of combustion and ventilation.
Periodic maintenance:
• Clean the heater with cleaning agent suitable for the unit’s construction material (i.e. stainless steel
cleaner).
• Lubricate moving parts.
• Inspect the gas supply piping system for any signs of corrosion or failure. Replace if necessary.
Before conducting maintenance on the heater disconnect the power and gas supply. When pressure testing
the gas supply piping system, follow these guidelines:
• At a test pressure in excess of 1/2 psig (3.5 kPa) the heater and ball shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of the system.
• At a test pressure equal or less than 1/2 psig (3.5 kPa) the heater must be isolated from the gas supply
piping system by closing it’s individual manual shutoff valve during any pressure testing of the gas supply
piping system.
Cleaning the main burner:
Gently use an air hose to blow any accumulated dust and/or dirt off the heater. Air hose pressure should
not exceed 30 psig.
Gently, pass an air hose over entire exposed area of the ceramic. A distance of 2’ to 4’ from unit is
recommended.
Gently place the air hose outlet into the venturi tube and allow the air to flow for approximately one minute.
During long periods of non-usage, remove or cover heater with a polyethylene bag and shut off gas supply. If
further service to the heater is desired, contact your representative or the factory.
NOTICE
Cleaning the heater elements with high pressure air may cause damage to the elements and equipment failure.
Do not blow out heating elements with high pressure air.
