Louisville Tin and Stove VCR701A-H ユーザーズマニュアル
PILOT ADJUSTMENT
The pilot flame can be observed by opening the pilot lighting
hole cover. The pilot flame should surround the top 3/8 to ½
inch of the thermocouple (see Figure 2). If the flame needs
adjusting, first locate the pilot adjustment screw cap and remove.
Adjustment screw is underneath (see Figure 1). To increase the
flame, turn the pilot adjustment screw counterclockwise .
To decrease the flame, turn the screw clockwise . NOTE:
The pilot is unregulated. If incoming line pressure is more than
7” w.c. Natural Gas or 11” w.c. for L.P. Gas, the pilot flame size
should be decreased.

RADIANTS AND GLASS PANELS
FOR ALL VCR MODELS
(See Figure 9 – Replacement Parts Section)
INSTALL GLASS AND RADIANTS AS FOLLOWS:
STEP 1. Remove three screws from under top of opening in
bezel frame assembly.
STEP 2. Pull top of bezel down and lay aside.
STEP 3. Remove glass from bottom pad in shipping carton.
STEP 4. Remove carton containing radiants from cavity of
combustion chamber.
STEP 5. Remove radiants from carton and install by tilting
backwards and lifting at the same time into opening. Place
the radiants on the burner radiants supports. The radiants
must be straight. Never operate heater if any radiant is
tilted to front or rear.

STEP 6. Install glass panels by inserting top edge into upper
retainer and lower into bottom support, and slide glass into
position. Do not allow a crack between the two glass panels.
Never operate heater with either glass missing or cracked.
STEP 7. Re-install bezel by placing bezel tabs over lower front
and swing bezel into position and secure with three screws.

MAIN BURNER ORIFICE
This appliance was shipped from the factory with an orifice
sized to give the correct gas input using the gas for which the
heater was equipped. There may be local conditions, such as
variation in gas pressure or BTU content of the gas, which
may be cause for a change in the orifice. The gas company
supplying the fuel or the installing contractor should check
the gas input rate.
sized to give the correct gas input using the gas for which the
heater was equipped. There may be local conditions, such as
variation in gas pressure or BTU content of the gas, which
may be cause for a change in the orifice. The gas company
supplying the fuel or the installing contractor should check
the gas input rate.
If the rate exceeds the “BTUH INPUT” on the rating plate by
5%, the orifice should be replaced with a smaller orifice by a
qualified technician to reduce the input to the rating plate
value.

qualified technician to reduce the input to the rating plate

The input rate may need to be adjusted for elevation. See the
following charts to determine the correct orifice size for your
Model Number and elevation. These orifice sizes are based
on a heating value of 1020 for Natural Gas and 2500 for L.P.
Gas.

CAUTION: As elevation increases, derating is necessary for
the safe and proper operation of this heater. Do not increase
the Btu input rate by increasing the orifice size or gas
pressure. Allow for elevation derating when sizing gas heating
equipment.
