Checking The Burner; Connecting A Gas Line - Lennox Hearth Products Elite CVF-LP Installation And Operation Manual

11.0 MOUNTING THE APPLIANCE - continued
Before tightening the wall-mounting screws fully, at this stage
it is recommended to check the horizontal alignment of the
appliance with a spirit level, as small adjustments can still be
made if necessary. When this has been checked, tighten all four
fixing screws fully.
To access the upper fixing screws insert a screwdriver either
through the round holes in the front of the outlet Grill (as shown
in Figure 3), or alternatively for easier access the outlet Grill
may be removed and the fixing screws accessed more directly
through the holes in the deflector baffle as shown in Figure 4.

1.0 CHECKING THE BURNER

There are no imitation fuel bed components, such as logs or
rocks, to install. The appliance features a ribbon burner which is
designed to produce a continuous band of flame over its length.
The burner should be visually inspected to ensure it is free from
any foreign matter. If it is necessary to clean or dust off the
burner then the glass door should be removed by removal of
the four retaining screws. Re-fit the glass door after cleaning or
inspection, ensuring a good seal.

13.0 CONNECTING A GAS LINE

Connecting directly to a unregulated propane tank
may cause an explosion.
Hold heater regulator with a wrench to prevent move-
ment when connecting to inlet piping.
A qualified gas appliance installer must connect the gas room
heater to the gas supply. Consult all local codes. Route gas
line using techniques and materials prescribed by local and/or
national codes. Only use pipe of 1/2" or greater diameter to allow
full gas volume to the gas fireplace. Undue pressure loss will
occur if the pipe is too small.
An external regulator must be used on all propane (L.P.G.)
heaters, in addition to the regulator fitted to the heater, to reduce
the supply tank pressure to 13" w.c. (maximum).
Figure 5
An ANSI approved manual shut-off valve and union must be
installed upstream of the heater within the fireplace cavity
when rigid pipe is used. Ensure that a sediment trap is installed
upstream of the heater (Figure 5) within the structure's piping
system to prevent moisture and contaminants from passing
through the pipe to the heater controls and burner. Failure to do
so could prevent the heater from operating reliably. The heater
gas inlet connection is 3/8" NPT at the regulator, located below
the burner, in the center of the heater. When tightening up the
joint to the regulator hold the regulator securely with a wrench
to prevent the regulator from moving.
