Keep the area clear and free from combustible materials, flammable liquids and
vapors. Do not block the flow of combustion air by blocking air vents or by storing
boxes or other items near the appliance.
Label all wires before disconnection when servicing controls. Wiring errors can
cause improper and dangerous operation.
Verify proper operation of the heater/boiler after any inspection or servicing the
appliance.
Heat Exchanger:
The heat exchanger should be visually checked at least once a year, or whenever necessary.
The heat exchanger can be viewed from the top of the unit by removing the draft hood. The fins on the heat
exchanger tubing should extend about 27/64 of an inch. Excessive burn off of fin height indicates poor heat
transfer, commonly caused by scaling (deposits of lime and other minerals) inside the tube. Look for corrosion
(usually a rusty-brown coating) commonly caused by cleaning solvent vapors or fumes in the combustion air
supply), or sooting (a fine black-gray powder caused by improper combustion, usually due to a partially blocked
stack or insufficient combustion air), or the affect of excessive condensation (usually evidenced by a greenish-
black cupro oxide caused by the acid formed by the mixing of combustion gases with the condensate).
Before removing draft hood, ensure that the gas and electrical power to the
heater/boiler is shut off.
Burner & Pilot Flame:
The burner and pilot flame should be checked frequently (it is recommended that the
unit be checked at least annually by a professional service technician). A yellow flame commonly indicates poor
combustion, and may cause soot deposits on the heat exchanger or inside the venting. When an excessively
yellow flame is present, inspect the burner orifices and heat exchanger for carbon deposits and foreign particles.
Yellow flame and sooting may be caused by inadequate combustion air, venting, or incorrect gas manifold
pressure. Refer to the burner and pilot flame Figure in the START-UP Section of this manual.
Gas Manifold Pressure:
Check the gas manifold pressure at least once per year to make sure it matches that
specified on the Name Plate, using an manometer (refer to START-UP Section for checking manifold pressure).
Vent System:
Inspect the venting system for proper size, horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion or any other deficiencies which could cause an unsafe condition. Check the inside
of the vent system for excessive sooting.
In so far as practical, close all building doors between the space in which the appliances are connected
to a common venting system and any area where any appliance which is not connected to the common
venting system is located. Test the system by turning on clothes dryers and any other appliance not
connected to the common venting system. Turn on all exhaust fans, including those used in range
hoods and bathroom exhausts, so they will operate at their maximum speed. Close fireplace dampers.
Place the appliance being tested into operation by following the proper lighting instructions. Adjust the
aquastat so the appliance will remain in operation for the duration of the test. After the main burner has
been in operation for at least five (5) minutes. inspect the venting for spillage. When it is determined the
unit is working without exhaust gasses spilling into the room, return doors, windows, fans, fireplace
dampers and any other gas-burning device to their normal condition of use.
Draft tests must be done with the appliance firing. Proper draft or airflow in the venting may be
determined by either of the following means:
MAINTENANCE & INSPECTION
This manual must be thoroughly reviewed and understood before servicing your A2000
heater/boiler. Installation and Service must be completed by a Qualified Installer, Service
Agency or Qualified Gas Supplier. If you have any questions which are not covered in the
manual, please contact Green Boiler Technologies or your local Representative.
