Installation

This unit meets the safe lighting performance criteria with the gas manifold and control assembly provided, as specified in the ANSI standards for gas-fired units. ANSI Z21.13/CSA 4.9 and ANSI Z21.10.3/CSA 4.3.

Locating the unit

1.Maintain all clearances from combustible construction when locating unit. See Clearances from Combustible Construction, this page.

2.Locate the unit so that if water connections should leak, water damage will not occur. When such locations

cannot	be avoided, install a		suitable	drain	pan that
is well-drained under		the	unit. The pan must not
restrict	combustion	air	flow.	The	appliance

manufacturer is not responsible for water damage in connection with this unit, or any of its components.

3.Install indoor units so that the ignition system components are protected from any water while operating or during service.

4.Appliances located in a residential garage and in adjacent spaces that open to the garage and are not part of the living space of a dwelling unit must be installed so that all burners and burner ignition devices

have	a	minimum	clearance of	not	less
than	18''	(46cm)	above the	floor.	The
appliance must be located or protected so that					it is
not subject to physical damage by a moving vehicle.

5.	DO NOT install this appliance in any location where
	gasoline or flammable vapors are likely to be present.
6.	The appliance must be installed on a level surface.
7.	Models 497 - 747 are approved for installation on
	combustible flooring using the approved combustible floor
	kits (reference Table 1A). Models 987 - 2067 are approved
	for installation on combustible flooring. Do not install
	appliances directly on carpeting.
8.	For outdoor models, you must install an optional vent
	kit. Instructions for mounting the vent kit are included
	in the venting section. Do not install outdoor models
	directly on the ground. You must install the outdoor
	unit on a concrete, brick, block, or other
