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" (91.4cm) is recommended.
Do not block outlet or inlet air openings on the front grill.
2. The DVC-35 minimum wall depth is 3/4" (19mm) and maximum
wall depth is 10" (254mm). The maximum wall depth may be
extended to 19" (483mm) using the model DV-1190 extended
flue kit. The use of tubes not supplied by the manufacturer
results in unsatisfactory performance.
3. The DVC-35 can be attached to the wall or recessed into
the wall up to 9 1/2" (241mm) in depth but the minimum 3/4"
(19mm) vent/air intake system wall depth must be maintained.
Example: If furnace is recessed into the wall at a depth of 9 1/2"
(241mm), the minimum wall depth must be 10 1/4" (260mm).
4. The wall in which the furnace is recessed has (0) zero clear-
ance 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" (102mm).
7. Ceiling clearance is 4" (201mm).
8. Floor and rear wall clearance is (0) zero inches.
9. Clearance of 18" (457mm) is required to sidewall or combus-
tible material when flush mounted SOR-1, side outlet register
is used.
10. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12" (305mm).

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 4.0" w.c. (.996kPa) 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
7.0" w.c. (1.743kPa). Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) 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" N.P.T. plugged tapping, accessible for test gauge connec-
tion, 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.
The vent terminal of this direct vent appliance shall be located
at least 9" (229mm) 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" (305mm) above grade. See
vent location, Figure 4.
WARNING: The nearest point of the vent cap should be a
minimum horizontal distance of six (6) feet (1.83m) from
any pressure regulator. In case of regulator malfunction,
the six (6) feet (1.83m) distance will reduce the chance of
gas entering the vent cap.
