DAMPER CLAMP INSTRUCTIONS
The damper clamp with hex bolt ( Fig. 6-2 ) is provided as a means to prevent
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. 6-3 and Fig. 6-4 ). Should the clamp not fi t, or
fail to provide the permanent vent opening listed in the table found above,
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
specifications. The damper must be
completely opened when operating
this gas appliance to achieve the best
ventilation possible.
