Install three (3) sheet metal screws 120° apart through the flexible vent and into the adaptor collar just
below the gear clamp to provide additional security to the connection.
3.
Route the flexible vent.
NOTE:
Ensure that the flexible vent is properly routed to provide the required clearance. Do NOT allow the flexible vent
to bend in a radius tighter than 5” (127 mm)
(
Figure 27B, Page 36
)
. Place the internal flexible vent spacers evenly
and avoid kinking the inner vent. Support horizontal sections of flexible vent with metal straps at 2 ft (0.61 m) intervals.
4.
Install firestop/spacers at ceiling and wall penetrations.
• SF4.5VF firestop/spacer for ceilings
• SF4.5HF firestop/spacer for walls
NOTE:
See the appropriate sections and figures shown throughout the venting section for installation
requirements.
5.
Attach the flexible vent to the termination.
NOTE:
Secure Flex
®
components can be purchased separately and attached to bulk lengths of Secure Flex
flexible vent cut to size at the job site. Attach the flexible vent to the Secure Flex terminations as it was attached
to the adaptor
(
Figure 27A
)
.
NOTE:
Attach Secure Flex vent to Secure Flex terminations only. Do NOT substitute Secure Vent
®
terminations
or Secure Vent adaptor for Secure Flex components. Secure Flex termination and adaptor collars are a
different circumference than Secure Vent collars. Secure Flex vent has an longer center tube to improve
ease-of-installation.

Complete the Field Wiring
CAUTION
The ground supply lead must be connected to the wire attached to the green ground screw
located on the outlet box (see wiring diagrams). Failure to do so will result in a potential
safety hazard. The appliance must be electrically grounded in accordance with local codes
or, in the absence of local codes, the National Electrical Code, ANSI/NFPA 70—latest
edition (in Canada, the current CSA C22.1 Canadian Electrical Code).
CAUTION
Label all wires prior to disconnection when servicing controls. Wiring errors can cause
improper and dangerous operation.
ATTENTION
Au moment de l’entretien des commandes, étiquetez tous les fils avant de les débrancher.
Des erreurs de cáblage peuvent entraîner un fonctionnement inadéquat et dangereux.
Verify proper operation after servicing.
S’assurer que l’appareil fonctionne adéquatement une fois l’entretien terminé.
The gas valve is set in place and pre-wired at the factory for the millivolt models.
