Checking The Burner; Connecting A Gas Line - Lennox Hearth Products Radium-NG Installation And Operation Manual

10.0 MOUNTING THE APPLIANCE - continued
Insert the wall mounting screws into the top wall plugs, taking
care to leave the screws protruding approximately 3/8" from the
wall. Now hang the appliance onto these screws through the two
keyhole shaped holes in the back panel of the appliance.
Insert the lower mounting screws into the lower wall plugs
through the corresponding depressed holes in the lower part of
the back panel. Do not tighten fully.
Before tightening the wall mounting screws fully, at this stage
it is recommended to check the horizontal alignment of the
appliance with a bubble 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 through
the holes in the deflector plates above the catalyst as shown in
Figure 3.

11.0 CHECKING THE BURNER

There are no imitation fuel bed components 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.

1.0 CONNECTING A GAS LINE

Connecting directly to a unregulated propane (L.P.G.)
tank may cause an explosion.

WARNING
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
IMPORTANT
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.
The installer must provide an ANSI approved manual shut off
valve, flex connector and 3/8" NPT fitting.
Route gas line using techniques and materials prescribed by
local and/or national codes. Only use pipe of 1/2" or greater size
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).

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 4) 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 right hand side of the heater.
When tightening up the joint to the regulator hold the regulator
securely with a wrench to prevent the regulator from moving.
