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 configuration 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 difficult as this clearance
is reduced.
• A 24” service clearance is required on the left side of KSZ series boilers equipped with float 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 flammable 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.
