Vent Requirements - Lopi Greenfield GSR2 Manual

12

Vent Requirements

• The gas appliance and vent system must be vented directly to the outside of the building, and never
be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each direct vent
gas appliance must use its own separate vent system.
•
In addition to the requirements listed here, follow the requirements provided with the vent.
•
When the vent passes through a wall a wall thimble is required. When the vent passes through a
ceiling a support box or firestop is required. When the vent passes through the roof, a roof flashing
and storm collar are required. Follow the instructions provided with the vent for installing these items.
NOTE: Wall thimbles may have different dimensions than what is required by this heater.
• The vent must maintain the required clearance to combustible materials to prevent a fire. Do not fill
air spaces with insulation.

Altitude Considerations
• Failure to adjust the air shutter properly may lead to improper combustion which can create a safety
hazard. Consult your dealer or installer if you suspect an improperly adjusted air shutter.
• This heater has been tested at altitudes ranging from sea level to 6,000 feet (1,800 M). In this testing
we have found that the heater, with its standard orifice, burns correctly with just an air shutter
adjustment.
