DAMPER CLAMP INSTRUCTIONS (IF APPLICABLE)
CLEANING AND SERVICING SAFETY INFORMATION
The damper clamp with hex bolt (Fig. 18-1) 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. 18-2 and Fig. 18-3). Should the clamp not fi t, or fail to provide
the permanent vent opening specifi ed in Table
3-1, have a permanent stop installed, remove the
damper blade, or have the damper cut to provide
the minimum permanent opening required.

Note: Regular cleaning and servicing will be necessary to ensure proper ODS pilot operation and proper burn
characteristics.
1. Always shut off the gas to the burner system while performing service work.
2. Allow the burner system to cool before servicing.
3. Installation, service, and repair must be done by an NFI Certifi ed or other qualifi ed professional
service technician. The appliance MUST be inspected before use, and cleaned at least annually to
prevent burner shutdown, sooting, odors, etc. by a qualifi ed professional service technician. It must
be checked for clean burning operation and proper ODS pilot appearance, with the correct tools to
service this unit. More frequent cleaning may be required. Excessive lint can build up on this unit from
carpeting, bedding material, pet hairs, or other particles in the air. It is imperative that all control components
and compartments, burner(s), and circulating air passageways of the appliance be kept clean and free of
all obstructions. The ODS pilot is especially sensitive to a dirty environment and will not function properly if
dirty. Make certain all air openings are clean and free of obstructions, including:
a. The air intake openings on the ODS pilot assembly.
b. The ODS pilot opening.
c. The air shutter on the burner.
WARNING: Failure to keep the primary air openings of the burner clean may result in sooting and property damage.
d. All of the ports on the burner. (See the CLEANING AND SERVICING section.)
4. Any safety screen or guard removed for servicing must be replaced prior to operating this burner
system.
