Leveling the boiler

To prevent air collecting in the boiler and to allow the condensate to
drain freely from the condensate pan, the boiler must be leveled.
CAUTION: Risk of boiler damage due to inadequate
load-bearing capacity of floor or unsuitable base.
▶ Make sure that the surface on which the solar storage
tank stands has sufficient load-bearing capacity.
▶ The boiler may stand on a base made of combustible
material but not on carpet.
▶ Place the boiler in its final position.
▶ Level the boiler horizontally by turning the adjustable feet and using
a level.

Openings for combustion air supply and venting

5 Openings for combustion air supply and venting
To ensure an adequate combustion air supply and venting of the heating
system, suitable measures must be taken in accordance with the
National Fuel Gas CodeNFPA 54 (ANSI Z223.1), Section 5.3, Air for
Combustion and Ventilation, or the local codes. In Canada the
regulations in accordance with CAN/CSA B149.1 and 2 Installation
Codes apply.
CAUTION: Risk of boiler damage and malfunctions due
to missing or inadequate openings for combustion air
and venting of the installation room.
The openings for combustion air supply and venting are
always required regardless of whether the combustion
air is supplied from the room (operation from room air)
or directly to the boiler through ducts (operation
independent of room air). Inadequate venting of the
installation room may result in excessive ambient
temperatures. This can damage the boiler.
Inadequate combustion air supply may cause
malfunctions.
▶ Make sure that air inlet or outlet vents are not closed
off or their size reduced and that they are adequately
dimensioned.
▶ Never operate the boiler unless faults are rectified
immediately.
▶ Inform the operator of any faults and their associated
risks.
CAUTION: Risk of boiler damage through contaminated
combustion air.
▶ Never use chlorinated cleaning agents or
halogenated hydrocarbons (such as those contained
in spray cans, solvents, cleaning agents, paints and
adhesives, for example).
▶ Never use or store chlorinated cleaning agents or
halogenated hydrocarbons in the installation room.
▶ Avoid very dusty atmospheres.
If impurities in the combustion air are possible (e.g.
installation near swimming pools, dry cleaners or
hairdressing salons), sealed combustion operation is
recommended.
CAUTION: Dangers posed by explosive and easily
combustible materials.
▶ Never use or store easily flammable materials (paper,
curtains, clothing, thinners, paints etc.) near the
boiler.
▶ Maintain a clearance of 16 inches from the boiler.
