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. at the valve outlet with the
inlet pressure to the valve from a minimum of 5.0" w.c. for the
purpose of input adjustment to a maximum of 7.0" w.c. Propane
gas models will have a manifold pressure approximately 10.0"
w.c. at the valve outlet with the inlet pressure to the valve from a
minimum of 11.0" w.c. for the purpose of input adjustment to a
maximum of 13.0" w.c.
a 1/8" N.P.T. plugged tapping, accessible for test gauge connection,
is located on the outlet side of the gas control.
The built-in regulator comes on at approximately 1/4th pressure
and full on in 10 seconds.
Safety Lockout
S8600H module provides 100 percent shutoff, or safety
lockout. If the pilot fails to light within 90 seconds, the
control system will shut down. The control system must
be reset by setting the thermostat below room temperature
for one minute or by turning off power to the module for
one minute.
Clearances
1. In selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper
installation.
2. The DV4T-59-1, 5" to 9" wall depth is the standard vent
kit provided with the DV-55IPT. See Accessories Page 6 to
order vent kits for wall depths of 8" to 12" or 12" to 19".
The use of tubes not supplied by the manufacturer results
in unsatisfactory performance.
3. The DV-55IPT can be attached to the wall or recessed into the
wall up to 4 inches in depth but the minimum 5 inches vent/air
intake system wall depth must be maintained. example: If
furnace is recessed into the wall at a depth of 4 inches, the
minimum wall depth must be 5 inches behind the furnace.
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, SOR-1 or SOK-1, the
furnace cannot be recessed into the wall.
6. Clearance to sidewall or combustible material is 4 inches.
7. Ceiling clearance is 4 inches.
8. Floor and rear wall clearance is (0) zero inches.
9. Clearance of 18 inches is required to sidewall or combustible
material when flush mounted SOR-1, side outlet register is
used. See Figure 4.
10. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 24 inches.
The vent terminal of a direct vent appliance with an input over
50,000 BTU per hour shall be located at least 12 inches 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 inches above grade.
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.
