R324-STIO Indoor Outdoor Ventless Gas Fireplace
Section 4: Installing the Gas Line
Fuel Consumption
Verify that your fireplace is compatible with your available 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 representative to purchase
a conversion kit.
Conversion kits must be installed by a qualified service technician.
Gas Pressure
Optimum appliance performance requires proper input pressures.
Gas line sizing requirements will be determined in ANSI 223.1 National Fuel Gas
Code in the USA and CAN/CGA B149 in Canada.
Pressure requirements:

Gas Pressure
Minimum Inlet Pressure
Manifold Presure
The manifold outlet pressure is set from the factory to the appropriate pressure but
should be verified.
To check pressures, control valves have a provision to remove a 1/8" N.PT. plug to
be fitted with a hose barb.
Montigo requires a service shut off valve be located in an accessible location to
isolate the gas supply.
Only install gas shut-off valves approved for use by the state, province, or other
governing body in which the fireplace is being installed.
GAS CONNECTION
The gas connection is located on the left side of the fireplace looking at the indoor
face of the unit.
Connect this line to a service shut of valve as per local code.
Make sure that the gas line as well as the shut of valve will be rated for 75,000 BTU
Purge all air out of the gas line prior to start up.
Flexible gas connectors must not exceed 3 feet in length, unless allowable within
local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
Check appliance connection, valve and valve train under normal operating pressure
with a commercially available leak check solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.
DANGER
After gas line is connected, each appliance connection, valve and valve train MUST
be checked while under normal operating pressure with either a Liquid Solution, or
Leak Detection Device, to locate any source of leak. Tighten any areas where
bubbling appears or a leak is detected until bubbling stops completely or leak is no
longer detected. DO NOT use a flame of any kind to test for leaks. A fire or explosion
will occur, causing serious injusy, property damage or death.
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.

Section 5: Electrical Connection
•
Connect 115 Volt 12 Amp power supply to the
connection box located on the right side bottom corner of
this fireplace.
•
There is 25 Feet of low voltage wire is coiled up on the
same side of this fireplace.
•
Run this low voltage wire to an on / off switch at a
location of your choice.
•
If this wire in inadequate in length you may replace this
wire with any Number 18 gage solid or stranded wire in
any length.
•
Do not splice these wires run a new wire directly from the
control board to the switch location.
•
Caution: Do not apply any power to these two wires.
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, discoloration or premature failure of
T.V. radio, and other electronic components.
CAUTION
When covering the upper metal portion of the fireplace, (as shown, Fig.16)
with a non-combustible material, Please Note: The decorative facing
materials may be subject to temperatures in excess of 250° F. This should
be considered when selecting facing materials.
