SECTION 2.
Locating and Clearances

2.1 Locating the 9600 HWG

The appliance should be located in an area

where leakage of any connections will not result in

damage to the area adjacent to the appliance or to

lower floors of the structure.

When such a location is not available, it is

recommended that a suitable drain pan, adequately

drained, be installed under the appliance.

The unit is design certified by AGA / CGA for

installation on combustible flooring; in basements; in

closets, utility rooms or alcoves. It must not be

installed on carpeting.

The location for the unit should be chosen with

regard to the vent pipe lengths, external plumbing,

ventilation of operating components and accessibility

for service and cleaning.

If there is potential for snow accumulation in your

area, both the vent terminals should be installed at an

appropriate level above grade (see Figures 2 and 3).

The following dimensions and requirements

should be met when choosing the location for the unit

(see Table 1):

Equivalent feet is determined by adding 10

linear feet for each 90° elbow and 5 linear feet for

each 45° elbow to be installed to the actual linear feet

of pipe required.

Example:

 8' of pipe, 2 x 45° elbows and a 90°

elbow.

Equivalent Feet:

 8' + (2 x 5') + (1 x 10') = 28.
