PERIODIC MAINTENANCE
Listed below are items that must be checked to insure safe reliable operations. Maintenance must be performed by a
qualified service or maintenance provider. Verify proper operation after servicing.
Warning: When servicing the controls, use exact, Factory authorized, replacement parts and label all wires
prior to disconnection. Verify proper operation after servicing. Incorrect parts substitution and wiring errors
can cause damage, improper operation, fire, carbon monoxide and other unexpected and unsafe conditions
that could result in fire, injury or death.
1. Examine the appliance and venting system at least once a year. Check more often in first year to determine
inspection interval. Check all joints and pipe connections for tightness, corrosion or deterioration. Clean screens in
the venting air intake system as required. Have the entire system, including, but not limited to, the burner, heat
exchanger and venting system, periodically inspected by a qualified service agency.
2. Using the view port, located on the blower base, visually check main burner flames at each start up after long
shutdown periods or at least every six months.
a. Normal Flame: A normal flame is blue, without yellow tips or flame lifting.
b. Yellow Tip: Yellow tip can be caused by blockage or partial obstruction of airflow to the burner.
c. Yellow Flames: Yellow flames can be caused by blockage of primary airflow to the burner or excess gas
input. This condition MUST be corrected immediately.
d. Lifting Flames: Lifting flames can be caused by over firing the burner(s) or excessive primary air.
e. Glowing Burner Media: Glowing burner media can be caused by a blocked air or burner condition resulting in
a reduced firing rate.
3. Exposure to Dusty or Dirty Combustion Air: An appliance installed in a dust or dirt contaminated atmosphere will
require cleaning of the burners on a 3 to 6 month schedule or more often, based on severity of contamination.
Contaminants can be drawn in with the combustion air. If an air filter box is used to remove dust or dirt, be certain
it does not restrict free airflow into the appliance and that the filters are periodically cleaned. Inadequate
combustion air or non-combustible particulate matter such as dust, dirt, dryer lint, concrete dust, dry wall dust or
the like can block burner ports and cause unsafe operation and a non-warrantable failure. To inspect and clean
the burner, a qualified serviceman or installer should use the procedures described in item 5 & 6 below.
4. Heat Exchanger Inspection and Cleaning: Any sign of soot on the heat exchanger or in the flue indicates the need
for increased inspection frequency and possible cleaning. Properly installed and adjusted units seldom need heat
exchanger cleaning. If a blocking amount of soot has formed or is forming, the heat exchanger must be cleaned
and soot-causing problem corrected. (The most common causes are restricted combustion air or excessive gas.)
A blocked heat exchanger can cause unsafe operation and will reduce efficiency. To inspect and clean the heat
exchanger, a qualified serviceman or installer should use the procedures described in item 5 & 6 below.
5. All gaskets on disassembled components must be replaced on reassembly with exact, Factory Authorized,
replacement parts only. Gasket kits are available from your Riverside Hydronics

6. Burner and/or Heat Exchanger Inspection and Cleaning Procedure:
a. Write notes and/or take pictures during this process to aid in correct reassembly.
b. Turn off main power to unit.
c. Turn off gas supply.
d. Remove the top access pan.
e. For models 400, 540, 750 and 1000, disconnect the main manual gas cock from the gas train.
f. For models 1200, 1600 and 2000, remove screws to disconnect the water outlet and gas supply escutcheon
plates and the combustion air supply pipe (if connected). Then remove screws and open upper latch to release
and remove the service half of the upper enclosure.
g. Remove the hot surface igniter and set safely aside (Do not touch the black heating surface of the igniter, as
oils from your hand can cause early failure. Take care during removal and reassembly, as the black heating
element is very easy to break when not installed.)
h. Remove the air control damper assembly from the blower inlet, if applicable, and set aside without
disconnecting wires.
