Finishing
A. Facing and Finishing - General Information
WARNING! Risk of Fire! Comply with all minimum clear-
ances to combustibles as specified. Framing closer than the
minimums listed must be constructed entirely of noncom-
bustible materials (i.e., steel studs, concrete board, etc.).
Splatter Guard
The splatter guard is a piece of corrugated material
used to protect the appliance during the installation
process before finishing work on the whole hearth is
complete. A splatter guard is factory-installed on PRI-
MO models. Splatter guards must be removed before
appliance is fired.
WARNING! Risk of Fire! Remove the splatter guard be-
fore lighting the appliance. Shut off gas to the appliance
when the splatter guard is in place to prevent accidental
operation.
Finishing Instructions
It is important to follow the framing and finishing instruc-
tions to ensure proper placement of fireplace into the sur-
rounding framing/finishing materials.
Wall sheathing materials 1/2 in. thick are specified
in this installation manual to properly align with the op-
tional finishing methods offered with this appliance. The
PRIMO may be finished to the appliance opening with 1/2
inch thick sheetrock.
•
Ensure that the one inch back clearance and one inch
side clearances are maintained.
WARNING! Risk of Fire! Maintain specified air space
clearances to combustibles. Inadequate air space could
cause overheating and fire.
WARNING! Risk of Fire, Explosion or Asphyxiation!
DO NOT use screws more than 3/4 inch long on lower
access cover panel. Longer screws may penetrate gas
line or damage valve or electrical components.
The appliance is designed to be used with 1/2 in. wall
sheathing materials such as drywall, plywood, wood
composites, or non-combustible materials.
Note: It is acceptable to use a high temperature silicone
sealant to adhere drywall to lower access cover panel.
Finish and Sealing Joints
All joints between the finished wall sheathing and the ap-
pliance must be sealed with non-combustible materials.
Sealants, such as caulk or mastic used to seal the gap
between the wall and the fireplace, should be rated at a
minimum continuous exposure to 300 ºF.
