Eliminate System Air; Fill The Boiler With Water; Install Gas Piping - FULTON EDR-1000 Installation And Operation Manual

SECTION 2
EDR-IOM-2014-0318
 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 Endura 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 confi gured 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.
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 shutoff valve

CAUTION
Care needs to be taken to eliminate
oxygen from the water system, as
excess oxygen in the system will
reduce the life of any boiler. The
boiler warranty does not cover heat
exchanger replacement due to oxygen
contamination of boiler water.
Heat exchanger failure due to
inappropriate water quality, foreign
matter or debris damage is not covered
under the warranty.
If the piping system attached to this
unit will be chemically cleaned, the
boiler must be disconnected from the
system and a bypass installed so that
the chemical cleaning solution does
not circulate through the boiler.
