Managing Heat Output
The heat output from the appliance can be controlled
by the position of the flue damper on vented fireplaces.
The damper setting should be fully closed for maximum
heat output, partially closed for less heat output and
fully open for minimum heat output.
The appliance may be used in a working solid fuel
burning fireplace with the fuel damper closed only if
unvented appliances are permitted by local state and
city codes. It may also be operated as a decorative
appliance whose prime function lies in the aesthetic
effect of the flames when installed in a solid fuel
burning fireplace with the flue damper open. If un-
vented heaters are not permitted, the fireplace vent
damper must be locked at a minimum free (vent) area
of 15 sq. ins.
Whenever the appliance is operated with the
fireplace's flue damper closed, glass doors - if
present - must be open and the outside air damper
and the ash dump (if the fireplace is equipped with
either one) must be closed.
The heat output from the appliance when operated as a
vent-free heater may be controlled by adjusting the
main gas valve. Reference lighting instructions on Page
14 and chart on Page 10 which shows inputs at all
settings.
The main gas valve may be adjusted anywhere be-
tween high and low to give the desired combination of
flame aesthetics and heat output.
