Section 5-1: FUEL CONVERSION

Verify that your fireplace is compatible with your available
Q
gas type. (Natural Gas or Propane shown by "N" or "L"
in your model number
If gas type is not compatible, contact your local Montigo
Q
representative to purchase a conversion kit.
Conversion kits must be installed by a qualified service
Q
technician.

Section 5-2: GAS PRESSURE

Optimum appliance performance requires proper input
Q
pressures.
Gas line sizing requirements will be determined in ANSI
Q
Z221.3 National Fuel Gas Code in the USA and CAN/
CGA B149 in Canada.
Pressure requirements are:
gas Pressure
Minimum inlet pressure
Manifold pressure
The manifold outlet pressure is set from the factory to
Q
the appropriate pressure but should be verified.
To check pressures, control valves have a provision to
Q
remove a 1/8" N.PT. plug to be fitted with a hose barb.
Montigo requires a service shut off valve be located in
Q
an accessible location to isolate the gas supply.
Q O nly install gas shut-off valves approved for use by the
Q
Q
state, province, or other governing body in which the
fireplace is being installed.
Section 5-3:
GAS CONNECTION
See Figure 22 below for location of gas line access.
Q
Flexible gas connectors must not exceed 3 feet in length,
Q
unless allowable within local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
Q
Purge all air out of gas line.
Q
Check appliance connection, valve and valve train under
Q
normal operating pressure with a commercially available
leak check solution.
DO nOT USE A FLAME OF AnY KInD TO TEST FOR LEAKS.

NOTICE
When pressure testing the fireplace,
Gas line, and input system follow the
appropriate local codes or your area.
DO NOT connect the fireplace to
pressures in excess of 1/2lb. This will
damage the gas control valve.
CAUTION
We recommend careful consideration
be given to the effects of elevated
mantel temperatures which may be in
excess of product design, for example:
candles, plastic or pictures. This can
cause melting, deformation, discolor-
ation or premature failure of T.V. radio,
and other electronic components.
