ATTENTION:
These instructions describe the installation of the optional
ridge vent kit. (Additional purchase required.) The ridge vent kit is
designed for use with the
HF
model (5.2 oz. cover) only. If you have the
C model or did not purchase the ridge vent kit, skip those installation
procedures when presented and continue as instructed.
Do not cut the film of the
HC
model to install ridge vent kit.
CUSTOMER-SUPPLIED END FRAME:
Construct the end frame for the
roll-up end panel using 4" x 4" wood posts. The doorframe materials are
supplied by the customer. If quality 4" x 4" lumber at the lengths needed
is not available, construct 2-ply wood beams using 2" x 6" boards secured
together with exterior grade bolts and nuts. Center the doorframe in the
end wall and dig the holes for the doorjambs.
Stagger all joints. Do not align.
Use treated lumber and set in
concrete for best results.
