INSTALLATION
GENERAL
1.
Follow all local codes, or in the absence of local codes, follow the most recent
edition
of the Na
tional
Fuel Gas Code: ANSI Z223.1/NFPA 54 in the USA or CAN/CSA B149.1 Natural Gas, Propane Installa
tion
Code in Canada.
2.
All gas micro-boiler require careful and correct installa
tion
to ensure safe and e
fficie
nt opera
tion.
This manual must be followed exactly.
Read the “Safety Guidelines”
Section.
3.
The manifold gas pressure is preset at the factory. It is computer controlled and should not need
adjustment.
4.
Maintain proper space for servicing. Install the unit so that it can be connected or removed easily.
Refer to the "Clearances"
Section
on p. 9 for proper clearances.
5.
The micro-boiler must be installed in a loca
tion
where the proper amount of combus
tible
air will be
available to it at all
times
without obs
tructions.
6.
The electrical c
onnection
requires a means of disc
onnection,
to terminate power to the micro-boiler
for servicing and safety purposes.
7.
Do not install the unit where the exhaust vent is poin
ting
into any opening in a building or where the
noise may disturb your neighbors. Make sure the vent termina
tion
meets the required distance by
local code from any doorway or opening to prevent exhaust from entering a building. (Refer to p. 19.)
8.
P
articles
from
flou
r, aerosols, and other contaminants may clog the air vent, build up and reduce
the
functions
of the rota
ting
fan, cause improper burning of the gas, or cause damage to the micro-
boiler.
Regularly ensure that the area around the unit is dust- or debris-free.
Regular maintenance is
recommended for these types of environment.
9.
The Hydro Smart 199 Gas Condensing Micro-Boiler is to be installed indoors only. This unit is
equipped with a thermistor and hi-limit switch for the exhaust g
as, detecting excess temperatures
within the
flue
and enabling the unit to safely stop opera
tions
if needed. These components are
always monitoring exhaust gas c
onditions
in order to prevent heat damage to ABS, PVC, CPVC, or
polypropylene
(Plas
tic)
ven
ting
if ABS, PVC, CPVC, or polypropylene is used. If the exhaust gas
temperature exceeds 140 °F, these components will enable the unit t
o safely stop operations.
•
The micro-boiler requires a 3" or 4” make-up intake air supply pipe.
The intake pipe must be
sealed
airtig
ht.
•
Air supply pipe can be made of ABS, PVC, CPVC, polypropylene, corrugated stainless steel, or
Category lll / IV stainless steel.
•
Sidewall ven
ting
is recommended for this boiler.
V
erti
cal
ven
ting
(roof termina
tion)
is acceptable.
•
The manufacturer recommends running the exhaust vent and the intake pipe as parallel as possible.
