Installation Instructions

Installation Manual

Page

Size the gas pipe appropriately to supply the necessary volume of gas

required for the micro-boiler using ANSI Z223.1/NFPA 54 in the USA or CAN/

CSA B149.1 in Canada or local codes. Otherwise, ow capabilities and

output temperatures will be limited.

This unit is not equipped with a regulator. A gas regulator is required for all

gas appliance installations.

You should always check and follow local codes and regulations. THIS IS

ONLY TO BE INSTALLED BY A LICENSED PROFESSIONAL.

-Gas Connections-

1. Install a manual gas shutoff valve, drip leg, exible gas line and regulator between the micro-boiler

and the gas supply line as pictured. The gas supply line shall be checked for leaks using code

approved methods.

2. When the gas connections are completed, it is necessary to perform a gas leak test either by

applying soapy water to all gas ttings and observing for bubbles or by using a gas leak detection

device.

• The micro-boiler and its individual shutoff valve must be disconnected from the gas supply

piping system during any pressure testing of that system at test pressures in excess of 1/2 psi

(3.5 kPa).

• The micro-boiler must be isolated from the gas supply piping system by closing its individual

manual shutoff valve during any pressure testing of the gas supply piping system at test

pressures equal to or less than 1/2 psi (3.5 kPa).

3. Always purge the gas line of any debris and/or water before connecting to the gas inlet.
