FLAME CHECK
A periodic check of the flames should be made. The pilot flame should always be present when the
gas logs are in operation. See Figure 4.
Rear Flames: The flames at the rear or at either side of the top log should be very similar, yellow in
color, and should be about 3" to 4" above the large rear log for natural gas logs and about 6"
for propane (LP) gas log sets.
Front Flame: The flame should be 1-1/2" to 2" high and touch the back of front log. This will
produce a red glow on this log.

WHEN USED AS A
HEATING APPLIANCE
HEAT OUTPUT
When used as a ventless heater, the flue damper of a solid-fuel burning non-combustible fireplace
must always be closed.
The heat output is controlled by the “ON/OFF” switch or wall thermostat, when using the ITT
Millivolt Valve. When using the -SIT Modulating or -SIT Manual Valve the heat output is controlled
by the dial with LOW to HIGH settings. The Vent-Free fireplace may be installed where permitted
by local, state, and city codes.
In the absence of local codes, the latest edition of the National Fuel Gas Code (ANSI Z223.1) must be
met.
