DAMPER CLAMP INSTRUCTIONS

Fig. 8-1 Damper clamp detail

Fig. 8-2 Damper open / closed

The damper clamp with hex bolt (Fig. 8-1) is provided as a

means to pre

vent full closure of the damper blade. The clamp

is easily attached to most damper blades with pliers or a

wrench, and must be permanently installed. The clamp is

designed to prevent accidental closure of the damper when

installed as illustrated (Fig. 8-2). Should the clamp not ﬁ t, or

fail to provide the permanent vent opening listed in Table 2,

have a permanent stop installed, remove the damper blade,

or have the damper cut to provide the minimum permanent

opening required.

Note: These are minimum damper opening speciﬁ cations.

The damper must be completely opened when

operating this gas appliance to achieve the best

ventilation possible.
