NBE RTB PHOENIX v16.0, Manual

INSTALLATION OF THE
BOILER:
General Guidelines
1. The boiler should only be installed by qualified installers
with a ”
Certificate for installation and service of small
biofuel plant ” and must be installed according to your local
and national building and construction codes.
2. The boiler must not be installed on any combustible
surfaces.
3.
Uninsulated smoke pipes should be kept to a minimum as
this will reduce draft and can cause condensation that will
damage the boiler. If installing a 90 degree bend in the
chimney make sure to reduce chimney horizontal length and
have a chimney clean out door available for easy cleaning
access. For better flow we recommend installing a 45
degree bend as this will allow for less ash to accumulate in
the chimney pipe.
4. The chimney draft should maintain a minimum of 10 PA
and be stable at both nominal and minimum power.
5. SHUNT or FLOWBOX W/ WEATHER COMPENSATION KIT
The boiler must be installed with either an approved shunt
or a flowbox with weather compensation valve and a boiler
return temperature sensor reference.
NOTE : You may lose
your warranty if failing to install an approved anti-
condensation circuit with your system. (
See approved
installation diagrams on pg 11-13)
6. Do not install this system with a draft stabilizer
The RTB Phoenix is equipped with an under pressure sensor
and inbuilt exhaust fan that will regulated the draft to
maintain 10 pascals in the chimney. If your building code
requires a draft stabilizer to be installed on this system we
advise to install the draft stabilizer low on the chimney to
prevent flue gasses from entering the boiler room.
Note:
Despite having an exhaust fan inbuilt in the boiler, the
chimney must nonetheless be capable on it’s own to deliver
a minimum of 10 pascals of under pressure.
