9. COMBUSTION AIR
Indoor combustion air must conform to the requirements
of the applicable code:
Canada Installation Code CAN/CGA-B149.1 or (USA.)
National Fuel Gas Code ANSI-Z223.1
In homes of normal construction, sufficient combustion air
can usually be obtained by air infiltration. The fireplace
insert must be installed in area that is free of excessive
dust and dirt and where ventilation is sufficient to provide
proper combustion of gas, proper venting and the
maintenance of safe operating temperatures. When
infiltration does not provide adequate air for combustion,
outside air shall be introduced as specified in the
installation codes.
The draft hood must be installed so as to be in the same
atmospheric pressure zone as the combustion air inlet to
the appliance.
To check if there is adequate air for combustion perform
the following procedure:
(See Figure 5)
I.
Close all windows and doors.
2. Turn all exhaust fans on high.
3.
Turn on fireplace insert.
4. To check for proper draft action a draft meter
with a minimum graduation of 0.01 inches of
water column is required. The meter is to be
attached to the 1/4 inch aluminum tube
originating in the draft hood using high
temperature silicone (tubing should not be
allowed to contact glass and unit should be
allowed to run for a minimum of 10 minutes;
area of sensing tube will become quite hot).
A minimum draft pressure of .02 inches of
water column is required to ensure that there
is no spillage at the draft diverter. This
number was arrived at through testing under
various severe conditions, actual vent
pressures under normal conditions will be
much higher. A draft pressure under .02 will
indicate either a blocked vent, down draft,
adverse house de-pressurization or improper
venting.
If there is not the proper draft then provide outside air as
instructed by the applicable code.
(Figure 5)
NOTE: DO NOT OBSTRUCT FLOW TO THE FRONT OF
THE FIREPLACE AS THIS COULD AFFECT
COMBUSTION AND BE A FIRE HAZARD. FAILURE TO
DO SO COULD RESULT IN PROPERTY DAMAGE,
INJURY AND/OR LOSS OF LIFE.
10. UNIT OPERATION & CHECK-OUT
Before trying to light the unit for the first time it is advisable
to purge the gas. Once the gas line is purged it is best to
wait a few minutes with a few open windows before trying
to light the fireplace. For detailed lighting instructions see
page
27.
Start-up Instructions:
1. Turn wall switch ( or thermostat) to the off
position.
2.
Turn gas valve to “PILOT” and depress.
3.
Press the red spark button repeatedly until a
steady pilot flame is present.
4.
Keep the “PILOT” position on the gas valve
depressed for approximately 45 seconds.
5.
Turn gas valve to the on position.
