Note: The gas line connection can be made of a 3/8 in. (12 mm) rigid tube or an approved flexible connector. It
is possible that other codes apply in your area. Please consult local authorities and the National Fuel Gas Code
ANSI.z223.1, NFPA54 in force. In Canada, consult the CAN/CGA-B149 (1 or 2).

INSTALLATION CODE

IMPORTANT
Install the main gas valve (stop valve) in an accessible location. The valve allows you to block the fireplace's
gas intake. Check building codes specifications regarding the location of the manual gas valve.
CAUTION
Use a propane gas-resistant joins sealant (metallic compound) to secure your gas lines.
Apply a light coat of joint sealing compound (metallic compound). Make attention to do not put excess sealant.
Excess sealant compound in pipes can lead to clogging the burner system.
We recommend installing a sediment trap in the supply line (figure 6.2). Install it where residues are not likely to
freeze. A sediment trap is designed to trap moisture and contaminants to prevent them from reaching the gas
burner control system.

• To make installation easier, a 12 in. (30 cm) flexible duct equipped with a manual valve is supplied with the
appliance. Install the 3/8 in. (12 mm) supply line and fasten it to the shutoff valve.
• Once gas line installation is completed, purge gas lines and check that all connections as well as the gas meter
(or tank) connected to the fireplace are tight. Make sure there are no leaks (see section 6.6).
• To adjust flame height, turn the HI/LO control knob located on the automatic valve.
WARNING:
Never use an open flame to check for gas leaks.
