Locating The Boiler - Dunkirk XEB-2 Installation, Operation & Maintenance Manual

If the boiler is part of a planned heating system, locate it where
shown on your plan. If boiler is to be part of an existing system, it
is usually best to put it where the old one was. If you plan to change
location, you will need additional materials as well as an adequate
base. The following rules apply:
1. The boiler must be level. Metal shims may be used under base
legs for final leveling.
2. Use a raised base if floor can become wet or damp.
3. The vent pipe connection should be as short as possible.
4. Additional clearances for service may exceed clearances for fire
protection. Always comply with the minimum fire protection
clearances shown on the boiler. An 18 inch clearance should
be maintained on any side where passage is required to access
for cleaning, servicing, inspection or replacement of any part
that may need attention. An 18 inch clearance is recommended
on the control side for servicing. Figure 2 and Table 2 shows
minimum clearances to combustible construction. Consult the
National Fuel Gas Code for further information.
5. Equipment shall be installed in a location in which the facilities
for ventilation permit satisfactory combustion of gas, proper
venting, and maintenance of ambient temperature at safe limits
under normal conditions of use. Equipment shall be located so
as not to interfere with proper circulation of air. When normal
infiltration does not provide the necessary air, outside air shall
be introduced (see "Fresh Air for Combustion").
6. Advise owner to keep air passages free of obstructions. Ven-
tilating and combustion air must enter boiler room without
restrictions.
7. The floor supporting the boiler must be noncombustible. If it is
combustible, please refer to Repair Parts List for the appropriate
Combustible Floor Base part number. We use a 2" Cladlite pad
as a combustible floor base. These are available from your local
supplier. Use 24" x 30" pad for 2-5 section boilers, and a mini-
mum 30" x 30" pad for 6-7 sections boilers. The boiler must be
centered on the combustible floor base.
8. The boiler shall be installed such that the automatic gas ignition
system components are protected from water (dripping, spray-
ing, rain, etc.) during appliance operation and service (circula-
tor replacement, control replacement, etc..)
