Installation Manual
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-boilers 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 micro-boiler 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 micro-boiler 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. 17 to 19).
8.
P articles from flou r, aerosols, clothes dryers and other airborne 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 micro-boiler is dust- or debris-
free. Regular maintenance is recommended for these types of environments. Sealed combus tion is
recommended too.
9. The Hydro Smart 120 micro-boiler is to be installed indoors only. The model is equipped with a
thermistor and hi-limit switch for the exhaust gas, det ecting excess temperatures within the flue and
enabling the micro-boiler to safely stop opera tion 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
(60 °C) these components will enable the micro-boiler to safely stop opera tion.
• The micro-boiler requires 3 inch, or 4 inch diameter intake air supply pipe. The intake pipe must
be sealed airtig ht.
• Air supply pipe can be made of aluminum fl exible tube, ABS, PVC, CPVC, Polypropylene,
corrugated stainless steel, or Category lll / IV stainless steel. Regarding exhaust pipe, please refer
to p.11 for detailed informa tion .
• 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.
