 Do not use open tanks or fi ttings
 Do not use oxygen permeable materials anywhere in
the water system
 Repair leaks in the system quickly
 Eliminate fi ttings wherever possible
 Use air elimination devices in system piping
 Eliminate System Air
NOTE:  There are no built-in boiler air eliminating
features.
Adhere to the following for air elimination:
1. The installation of an air separator and air eliminator (air
vent) is required.
2. To prevent scale corrosion in boiler and associated
piping, make up water must be kept to a minimum. This
is best achieved by ensuring immediate repair of all
leaks and that system pressure is maintained.
3. If a sealed diaphragm-type expansion tank is used,
install an air eliminator in the hot water piping at the air
separator.
4. If an air cushion type expansion tank is used, pipe tank
directly into boiler supply.
5. On multi-zoned systems (or a system with both space
and domestic water heating), air elimination must be
provided either in the common piping or on every loop.
6. When the boiler is installed at a higher level than
baseboard radiation (if used), air elimination must be
provided directly above the unit.
Fill the Boiler With Water
To be sure that the boiler is not air-bound, open the pressure-
relief valve located at the rear of the boiler. Leave the relief
valve open until a steady fl ow of water is observed. Close the
valve and fi nish fi lling the system.
Install Gas Piping
The Vantage boiler is factory test fi red and combustion is
adjusted per the boiler data plate and test fi re sheet.
The gas train components are UL-795 certifi ed to operate at
specifi c gas pressure requirements. The specifi c requirements
for each boiler are called out on the boiler nameplate, located
on the back of the boiler. Parameters depend on fuel(s) for
which the boiler is designed.
Adhere to the following for gas piping installation:
1. See Table 3 for required natural gas pipe size, based on
overall length of pipe from the meter plus equivalent
length of all fi ttings. Approximate sizing may be based
on 1,020 BTU for 1 cubic foot of natural gas.
2. Piping must be installed such that no piping stresses
are transmitted to the boiler. The boiler cannot be used
as a pipe anchor.
3. The boiler and all gas piping connections must be
pressure-tested and checked for leaks before being
placed into service. Test with compressed air or inert
gas if possible.
4. The boiler must be disconnected at the boiler manual
