Venting

Adhere to the following venting requirements:
1. The Endura boiler can operate to the combined intake and fl ue pressure
drops without altering standard capacities: See Table 4.
2. The pressure drop readings at the boiler exhaust connection and air intake
connection cannot exceed the maximum value stated in Table 4. This
means that the combined pressure drop through the air intake venting (if
installed) and exhaust venting cannot exceed the maximum value stated
in Table 4; this is typically approximately 35 feet (10.6 m) with 4 elbows of
connection size piping. Alternative distances and number of elbows may
be appropriate if determined by the venting designer to be within the
pressure drop ranges in Table 4. If pressure drop is exceeded, the boiler
may have to be de-rated or operational issues will result. Also, the pressure
at the boiler exhaust connection must not exceed a maximum negative
value as stated in the table. This pressure must remain relatively constant
throughout the operation of the boiler. Drastic draft changes during
operation may result in generation of excessive carbon monoxide or soot.
To decrease termination noise, increase the venting size at the termination
points. This will slow the air velocity causing a reduction in noise. Do not
terminate the venting in an enclosed area. Care must be taken when
selecting the orientation of the terminations.

NOTE: Consult your venting pipe supplier for assistance with sizing of vent
materials and other potentially required accessories.
3. Do not use boot tees or bullhead tees.
4. Barometric dampers should never be used in a condensing boiler
application even if the draft is negative, this is because barometric
dampers physically open to the mechanical room and it will be possible for
fl ue gas condensate to drain down the outside of the stack.
5. The air intake system must be designed to prevent any moisture from
draining to the boiler.
6. The layout of the piping used for air intake and exhaust must be done in a
way that facilitates smooth travel and natural fl ow. Performing a pressure
drop calculation isn't enough information to make sure a draft system will
perform adequately. Good practice must be used by the designer and
installer. Some recommendations:

Avoid sharp turns, boot tees, bullhead tees, back-to-back 90
degree elbows, short radius elbows especially right at the
connections to the boilers

Avoid extensive direction changes (fl ue gases being required
