OPENING
Header is provided with furnace. However, if it is desired
to finish wall before furnace is delivered, the header may
be ordered and installed prior to delivery of furnace.
Note: Construction deeper than standard (2x4 stud) may
create installation problem. Contact Empire for
additional information. GWT-50 will not work on walls
with deeper than 2x4 construction.
* Purchase Locally
Note: Empire has a policy of constantly improving quality
and performance of its appliances, therefore, materials and
specifications are subject to change without notice.
Note: Units do not come with thermostats.
Note: A vent safety switch is standard on all models, automatically
shutting off the heater in the event of a blocked flue or incorrect
installation. (Example: Attaching a 90° elbow directly to the draft
diverter is an incorrect installation.) The flue pipe diameter must be as
large as the flue collar on the draft diverter and run as directly as
possible to the chimney with a minimum of elbows. Any flue pipe
passing through walls and roof must be "B" Type vent. The chimney
must extend at least two feet above the roof and any object or
building within ten feet of the chimney.
