WARNING!
Gas Supply
2.0 Installation • Gas Supply
Improperly connected gas lines may result in fire, explosion,
poisonous fumes, toxic gases, asphyxiation and death.
Connect gas lines in accordance with national, provincial and local
codes.
The gas supply to the infra-red heater must be connected and tested in accordance with national, provincial and local
codes along with the guidelines in the Brant Radiant Heaters PH Series Manual. Refer to the latest edition of the CAN/
CSA B149.1 and 2.
Important!
Before connecting the gas supply to the infra-red heater(s):
• Check for conditions such as drafts or other variables with might cause excessive movement of the unit
and cause damage to the gas connection. Ensure that the unit is securely mounted and connect the gas
with an approved connection device suitable for the environment of use.
• Check that the gas piping and service has the capacity to handle the load of all heaters being installed, as
well as any other gas appliances being connected to the supply line.
• Check that the main gas supply line is of proper diameter to supply the required fuel pressures.
• If utilizing used pipe, verify that its condition is clean and comparable to a new pipe. Test all gas supply
lines in accordance with local codes.
• Test and confirm that the inlet pressures are correct. Refer to the rating plate for required minimum and
maximum pressures. The gas supply pipe must be of sufficient size to provide the required
capacity and inlet pressure to the heater (if necessary, consult the local gas company).
• For 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.
• For test pressures equal to or less than 1/2 psig (3.5 kPa), the heater must be isolated from the gas
supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas
supply piping system.
