3) Make sure that the boiler is correctly sized. Use an industry accepted sizing method such as the I=B=R Guide RHH

published by the Air-Conditioning, Heating and Refrigeration Institute (AHRI).

4) In some cases, boilers installed at altitudes above 2000ft may require a different burner conguration from that at sea level.

Consult the local Crown representative for more information.

IV Locating the Boiler

1) Clearances:

• Observe the minimum clearances shown below. Except as noted, these clearances apply to all combustible con-

struction, as well as noncombustible walls, ceilings and doors. Also see Figure 2.

Front – 24”

Left Side – 6” (24” for Boilers Equipped with Float Type Low Water Cut-offs)

Right Side – 6” (24” for Boilers Equipped with Tankless Heaters)

Rear – 6” (24” for boilers connected to indirect water heaters)

Top – 6”

Single Wall Chimney Connector (to combustible construction) - 18”

• A 24” service clearance from the jacket is recommended from the top of the boiler. This clearance may be

reduced to that shown above; however, servicing the boiler will become increasingly difcult as this clearance

is reduced.

• A 24” service clearance is required on the left side of KSZ series boilers equipped with oat type low water cut-

offs. This is to facilitate low water cut-off maintenance.

2) If listed Type L vent is used, follow vent pipe manufacturer recommendations for minimum clearances.

3) Do not install this boiler directly on a combustible surface. Where it is desired to install the KSZ over a non-carpeted com-

bustible surface, install the boiler on the base shown in Figure 3.

4) Do not install this boiler in a location where gasoline or other ammable vapors or liquids will be stored or used. Do not

install this boiler in an area where large amounts of airborne dust will be present, such as a workshop.

WARNING

FAILURE TO OBSERVE THE FOLLOWING LOCATION REQUIREMENTS COULD RESULT

IN PROPERTY DAMAGE, A FIRE, EXPLOSION OR CARBON MONOXIDE (CO) HAZARD.
