INTRODUCTION
The Fireplace models covered in this manual
are Direct-Vent sealed combustion gas fire-
place heaters designed for residential applica-
tion. Direct-Vent appliances operate with the
combustion chamber completely isolated from
the indoor environment. All air for combus-
tion is brought in from the outside and ex-
haust gases are vented through the same
direct vent, vent system.

The millivolt appliances are designed to oper-
ate on either natural or propane gas. A millivolt
gas control valve with piezo ignition system
provides safe, efficient operation. If any op-
tional accessories which require electrical

must be provided at the time of appliance
installation.
The electronic appliances are designed to op-
erate on either natural or propane gas. An
electronic intermittent pilot system provides
safe, efficient operation. External electrical
power is required to operate these units.

M91 in both USA and Canada, as vented gas
fireplace heaters.

trical wiring must comply with local codes. In
the absence of local codes, installation must
