Leak Testing The Gas Line; Checking The Pilot Flame; Checking The Draft; Adjusting The Air Shutter - Lopi Heritage Bay Insert Owner's Manual

INALIZING THE
4 Turn on gas to the
heater. Leak test all
gas joints prior to
starting the
appliance. Start the
pilot. Start the main
burner. Leak test all
gas joints again.
5 Check the pilot flame
to make sure it looks
like the illustration to
the right. Adjust the
pilot flame if
necessary.
6 Let the heater burn
for fifteen minutes.
Adjust the air shutter,
if necessary, to
achieve the correct
looking flame (see
the illustration to the
right).
¥ The air shutter
adjusts the amount of
air that mixes with
the gas before it exits
the burner holes. It
is used to fine-tune
the flame for
differences in
altitude and vent
configuration.
! If the air shutter is in its fully open position, yet the flames remain sooty, shut off gas to the heater
and contact your dealer for a remedy.
7 Ensure the heater establishes a draft. If the heater unexpectedly shuts off 5 to 25 minutes after
starting, the heater may not be drafting. The cause: negative pressure. Typically, re-starting the
heater five minutes after the shutoff will overcome the negative pressure and establish a draft.
However, if this does not work, you may wish to open a door or window near the heater. This will
allow in enough air in to overcome any negative pressure. Once drafting is initiated, the heater will
work properly without having to re-start the heater or allow in outside air. This is due to the heat
generated by the pilot.
Possible Causes of Negative Pressure:
¥ Exhaust fans (Jenn-Aire type fans in kitchens, bathroom fans)
¥ Vent termination located near a down draft or against prevailing winds
¥ Internal home pressure characteristics (multiple fireplaces, etc...)
8 Turn the flame adjust knob to its highest position - the flames should be approximately 10" tall.
Check the flame on low position. The flames should burn off of each burner hole. If the heater does
not work correctly, contact your dealer for a remedy.
9 Give this manual to the home owner and fully explain the operation of this heater.

NSTALLATION
The pilot flame should impinge the top 3/8Ó (10 mm)
of the thermopile. If it does not, you may need to
turn the pilot up.
Thermopile
3/8Ó (10 mm)
Locate the air shutter adjustment
lever behind the gas control valve.
Move it up or down until the flame
looks correct. Pushing up gives the
flame more air (making it bluer).
Pulling it down cuts air down,
making it more orange.
NOTE: If the air control is all the
way up, yet the flames remain
sooty, shut off gas to the fireplace
and contact a qualified gas service
technician.
Correct
Flames should be blue at the
base, yellow-orange on the top.
