Figure 5. Outdoor Top Installation

For installations in Florida and Texas,

that must

comply with the Florida or Texas Building Code, follow

the directions shown in

Figure 7

for the installation of

hurricane tie-down brackets for all models.

Indoor Heater Installation

The heater is also design-certified for indoor installation

when equipped with the approved drafthood.
For Canada, indoor installation is restricted to an enclosure

that is not occupied and does not directly communicate

with an occupied area. Refer to the latest edition of CAN/

CSA-B149 for specific requirements. Locate heater as

close as is practical to a chimney or gas vent. Heater

must always be vented to the outside. See section

"Vent

Piping" on page 13

for details. Minimum allowable

space is shown on the nameplate.

WARNING:

Indoor heaters require a drafthood that

must be connected to a vent pipe and properly vented to

the outside. Failure to follow this procedure can cause

fire or fatal carbon monoxide poisoning.

Outdoor and Indoor Stacks

The outdoor and indoor stacks are optional equipment

and do not come standard with the heater.

Refer to

installation instructions inside box for instructions on

how to install outdoor/indoor stack.

functions as the vent termination.
