NOTICE: IF PILOT DOES NOT LIGHT

THE GAS SUPPLY HOSE MAY REQUIRE PURGING

If the heater pilot does not light within a minute, it may be due to air in the gas supply hose. Air must be purged

from the hose.

According to The Canadian B149.1-00 Natural Gas and Propane Installation Code:

5.23.7 When a piping or tube system is to be purged to the outdoors,

a. The purging line shall not terminate closer that 10 ft (3 m) from either a building or air intake;

b. The purging point shall be under the constant supervision of a competent person who shall control the purge by a

quarter turn lever handle valve within 5 ft (1.5 m) of the purge point. Such a valve shall have an attached operating

handle. No other valve shall be used to control or terminate the purge; and

c. Smoking shall not be permitted, and maximum precautions shall be taken to either remove or shut off any source

or potential source of ignition prior to commencing the purge.

and

5.23.9 When all piping and tubing systems and hose have been purged, the appliance piping shall be purged and the pilot burner

lighted.

A qualified person can purge the gas supply hose as follows:

1. Adhere to all requirements of the B149.1-00

Natural Gas and Propane Installation Code

as listed above.

place at least 10 ft (3 m) from a building or

or other tool that can scratch/damage the

surface of the quick disconnect valve

‘seat’.)
