Fuel Supply + Manifold Pressure Checking - Montigo 30FID Installation & Maintenance Manual

Fuel Supply + Manifold Pressure Checking

It's imperative that you verify that the supply pressure to your
appliance is adequate and that the valve is supplying the
correct pressure to the pilot and main burner. The pilot burner
operates at line pressure and may need further adjustment.
The valve outlet pressure is set by the manufacturer of the
valve but should be verified upon install. Follow the following
steps to perform this system check. Inlet pressure must be
checked with fireplace burning.
1). Remove the 2 screws from the Valve Mounting Bracket so that
the valve can be swung away from the unit. The Shut off lever
needs to be in the "off" position to be able to swing the valve out
of the valve control box.

4). The emergency Shut-off valve needs to be placed in the
"ON" position, see section for operation. The pressure tap on the
left is to be used to measure supply line pressure. Refer to the
specifications at the beginning of this manual for the gas pressure
specs. Be sure to close and leak test all potential leak areas prior
to closing in the install. Using the remote, turn the main burner on.
Check the inlet pressure and the manifold pressure on high and
low. Refer to specification sheet for acceptable values. Remove
rubber tubes, close taps and check for leaks. Close emergency
shut-off valve reinstall the valve mounting bracket. Make sure
wires and pilot gas lines are not pinched or kinked. Check pilot
gas line for leaks.
