Gas Supply

!WARNING

Improperly connected gas lines may result in fire, explosion, poisonous fumes, toxic gases, asphyxiation and death. Connect gas lines in accordance to national, state, provincial and local codes.

The gas supply to the infra-red heater must be connected and tested in accordance with national, state, provincial and local codes along with the guidelines in this manual. Refer to the latest edition of the ANSI Z223.1 (NFPA 54) Standard.

Important! Before connecting the gas supply to the infra-red heater(s):

•Check for conditions such as drafts or other variables which 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.

Chart 2.2 - Manifold Pressure

•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 inlet pressures are correct. Refer to the rating plate for required minimum and maximum pressures (see Chart 2.2). 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 test pressures 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.

•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 it’s individual manual shutoff valve during any pressure testing of the gas supply piping system.

Type of	Required Manifold	Minimum Inlet	Maximum Inlet
Gas	Pressure	Pressure	Pressure
Natural	5.0 in. W.C.P.	6.0 in. W.C.P.	14.0 in. W.C.P.
Liquefied Petroleum	10.0 in. W.C.P.	11.0 in. W.C.P.	14.0 in. W.C.P.

Note: Check manifold pressure at the tap on the ball shutoff valve. Readings will be above atmospheric pressure during operation.

Pressure Equivalents: 1 in. W.C.P. equals .058 oz./sq. in. equals 2.49 Mbar.
