Checking Manifold Pressure
Both Propane and Natural gas valves have a
pressure of approximately 4.0” w.c. (.996kPa) for
A1/8” N.P.T. plugged tapping, accessible for test gauge connection, is located on the outlet side of the gas control.
The
CLEARANCES
Clearances
1.In selecting a location for installation, it is necessary to provide adequate accessibility clearances for servicing and proper installation. A front clearance of 36” is recommended. Do not block outlet or inlet air openings on the front grill.
2.The
3.The
4.The wall in which the furnace is recessed has (0) zero clearance to the furnace sides and top.
5.When using side discharge registers,
6.Clearance to sidewall or combustible material is 4”.
7.Ceiling clearance is 4”.
8.Floor and rear wall clearance is (0) zero inches.
9.Clearance of 18” is required to sidewall or combustible material when flush mounted
10.The minimum distance from the center of the vent cap to the nearest outside corner or obstruction is 12”.
Figure 4
The vent terminal of this direct vent appliance shall be located at least 9” from any opening through which flue gases could enter a building. The bottom of the vent terminal and the air intake shall be located at least 12” above grade. See vent location, Figure 4.
WARNING: The nearest point of the vent cap should be a minimum horizontal distant of six (6) feet from any pressure regulator. In case of regulator malfunction, the six (6) feet distance will reduce the chance of gas entering the vent cap.
