EYF Series Unvented Gas Log Set INSTALLATION
The dimensions shown in Figures 4 through 10 and defined in the fireplace
manufacturer's instructions are minimum clearances to maintain when
installing this heater. Left and right clearances are determined when
facing the front of the heater.
When heater is installed into a ventless firebox, minimum clearances,
as specified by the ventless firebox manufacturer, must be met.
Follow these instructions carefully to ensure safe installation. Failure
to follow instructions exactly can create a fire hazard.
Sidewall and ceiling clearances: The sides of the fire-
place opening must be at least 16" from any combustible
wall. The ceiling must be at least 42" from the top of the
fireplace opening.
