FLUEING INTRODUCTION
The GF1500LST uses the "balanced flue" technology Co-Axial system. The inner liner vents products of combustion to the outside while the outer liner draws
outside combustion air into the combustion chamber thereby eliminating the need to use heated room air for combustion and losing warm room air up the flue.
Note: These flue pipes must not be connected to any other appliance.
The gas appliance and flue system must be vented directly to the outside of the building, and never be attached to a flue system serving a separate solid fuel
or gas burning appliance. Each direct vent gas appliance must use it's own separate flue system. Common flue systems are prohibited.
FLUEING ARRANGEMENT FOR HORIZONTAL TERMINATIONS
The diagram shows all allowable combinations of vertical runs with horizontal terminations, using one 90
o
(two 45
o
elbows equal one 90
o
elbow).
Note: Must use optional rigid pipe adapter (Part# 770-994) when using Simpson DuraVent Only.
• Maintain clearances to combustibles as listed in "Clearances" section
• Horizontal flue must be supported every 0.9m
• A flue guard should be used whenever the termination is lower than the specified minimum or as per local codes.
• Flex system can only be used up to 3m - otherwise rigid system must be used.
