NANOV TOP DV GAS APPLIANCE INSTALLATION INSTRUCTIONS
b. Burner Orifice
Completely loosen the nut securing the orifice
with a 5/8 wrench (refer to Figure 33). Remove
the orifice and replace it with the propane orifice.
Tighten the nut.
c.
To adjust the air shutter at the base of the burner
tube/neck, loosen the 1/4 screw using either a
1/4 nut driver or stubby screwdriver. Slide the
shutter fully open and secure. See Figure 33.
Figure 33 - Burner Orifice
d.
Return the burner to its position on the orifice
and secure it with four screws, one at each corner.
Test for leaks between the valve and burner with
the burner lit as indicated in Step 6.
Step 6 - Leak Test
a.
This is important!
Propane (LP) gas is heavy. If
there is an incomplete gas line connection the
gas could leak and settle to the lowest point and
then accumulate. Such a situation could be
hazardous. Do not proceed until all connections
are checked and any leaks eliminated!
b.
Turn on the gas.
c.
Test
all
gas connections for possible leaks by
using a soap/water solution or Sniffer (turn on
and calibrate the Sniffer, then place the sensor
end of the sniffer within 1/2 of each connection).
If the soap/water solution or Sniffer indicates there
is a leak, tighten and seal the connection and
then retest.
d.
Turn the position indicator to the PILOT position
and depress. Press the push button ignitor and
light the safety pilot. Continue holding the position
indicator in the depressed position until the pilot
stays lit (approximately 45 seconds). Test for leaks
at the pilot assembly using one of the methods in
Step 6c.
e.
Turn the position indicator to the ON position
and test for leaks at the valve and the burner orifice
using one of the methods in Step 6c.
Step 7 - Checking the Pressure
a.
The gas input, inlet gas supply pressure and
manifold pressure must be as indicated on the
rating label located in the control area of the
appliance.
Any other input, inlet pressure or
manifold pressure could cause your gas
appliance to operate other than intended and
could cause serious injury or property damage.
b. Inlet Pressure
Verify that the gas valve is set at the PILOT
position. Verify the inlet gas supply pressure by
loosening the screw located inside the inlet
pressure tap. See Figure 34. Connect a
Manometer to the inlet pressure tap by pushing
the Manometer hose over the pressure tap. Turn
the valve to the ON position and turn the burner
on (with wall switch, remote, etc.). If the inlet gas
pressure is incorrect, do not adjust without
specific approval and instruction from the gas
supplier. Changing the inlet pressure may affect
other appliances in the residence. When
finished, return the valve to the PILOT position,
disconnect the Manometer and tighten the inlet
pressure tap screw.
Figure 34 - Valve Pressure Test
c. Outlet Pressure
Verify that the gas valve is set at the PILOT
position. Verify the manifold pressure by
loosening the screw located inside the outlet
pressure tap. See Figure 34. Connect a
Manometer to the outlet pressure tab by pushing
the Manometer hose over the pressure tap. Turn
the valve to the ON position, ignite the
appliance, and ensure that the pressure is
between 3 and 4 water column (optimum
pressure is 3.5 WC) for natural gas and
