Through Roof Framing
Maintain 10" opening relative to the pitch of the
roof.
To prevent water seepage install the flashing with
upper portion slid under the roofing material and the
lower portion over the roofing material.
NOTE: Do not fasten down until the final
adjustments to the vent have been made.
MOBILE HOME INSTALLATION
Direct Vent appliances installed in Mobile Homes
must be secured to the floor in a minimum of two
locations. All four legs have leveling bolts that can
be removed and a lag screw can be used to secure
the heater to the floor and/or hearth pad.
For proper venting, see Figure 6, Figure 14, and
