GENEVA SERIES B-VENT GAS APPLIANCE
4. Firestop Spacer/Vent Installation
Frame an opening and install a firestop spacer
whenever the vent penetrates a ceiling/floor area, as
shown in Figure 8. Frame the opening with the same
sized lumber as used in the ceiling/floor joists. Unless
the flue is offset, the hole should be directly above the
appliance. DO NOT pack insulation around the vent.
Assemble vent sections as per manufacturer’s
specifications.

3. 90° Elbows
A maximum of four 90° elbows may be used on this
appliance when used in conjunction with the fixed glass
doors shown below. See Figure 7.

Figure 7 - 90° Elbows
5. Chase/Termination Installation
Figure 9 and Table 1 specify minimum vent heights for
various pitched roofs. Vent sections may have to be
cut to a certain length.
These vent heights are necessary for safety and do
not ensure draft-free operation. Trees, buildings,
adjoining roof lines, adverse conditions, etc. may create
a need for a taller vent should down drafting occur.

Note:
To ensure proper operation, verify all venting
and the termination are unobstructed.
