3.3.3 Clearances

If the boiler is to be installed near combustible
surfaces, the minimum clearances shown in the table
below must be maintained.
Failure to provide for the service access clearances,
even with non-combustible surfaces, may cause future
problems servicing the boiler.
The boiler must be installed in a space large in
comparison to the boiler as described in Section 6.3 of
the National Fuel Gas Code, ANSI Z223.1, latest
edition.
No pipes,
ducts, etc. in
this area.

† "C" Do not put pipes, ducts, etc. in this area above
the boiler.
CAUTION!
Bumping hazard from overhead ducts! Install all
components with adequate vertical clearances.
* Clearance depends upon vent configuration.
** Service access need be only on one side of a
boiler or row of boilers. Boilers may be installed
immediately adjacent to each other. However, P-K
recommends this clearance between each boiler
when there is insufficient access at the rear to allow
for service and adjustment.
