Method of Installing a Tee Fitting Sediment Trap
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be placed
immediately upstream of the gas supply connection to the appliance.
2. The appliance and its appliance main gas valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping system by
closing its equipment shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal to or less than 1/2 psig
(3.5 kPa).
Attention! If one of the procedures results in pressures in excess of 1/2
psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will result in a
hazardous condition.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure regulator in
the gas valve. Natural gas models will have a manifold pressure of
approximately 3.5" w.c. (.871kPa) for maximum input or 1.7" w.c.
(.423kPa) for minimum input at the valve outlet with the inlet pressure to
the valve from a minimum of 5.0" w.c. (1.245kPa) for the purpose of input
adjustment to a maximum of 10.5" (2.615kPa) w.c. Propane gas models
will have a manifold pressure approximately 10.0"w.c. (2.49kPa) for
maximum input or 5.9" w.c. (1.469kPa) for minimum input at the valve
outlet with the inlet pressure to the valve from a minimum of 11.0" w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of 13.0"
w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge connection,
is located on the outlet side of the gas control.
Installation on Rugs and Tile
If this appliance is to be installed directly on carpeting, tile, or other
combustible material, other than wood flooring, the appliance shall be
installed on a metal or wood panel extending the full width and depth of
the appliance.
The base referred to above does not mean the fire-proof base as used on
wood stoves. The protection is primarily for rugs that may be extremely
thick and light-color tile that can discolor.
Clearances (Figures 2, 3, 4 and 5)
In selecting a location for installation, it is necessary to provide adequate
accessibility clearances for servicing and proper operation.
Locating and Venting the Direct Vent Fireplace
Clearances: When facing the front of the direct vent fireplace the
minimum clearances to combustible construction (material) are the
following:
Top of appliance (ceiling) 36 (inches)
Rear Wall 2 (inches)
Side Wall 6 (inches)
Heater Corners (45
°
angle) to Wall 4 (inches)
Floor 0 (inches)
