Matrix Installation and Operation Instructions
16.0 ANNUAL MAINTENANCE AND INSPECTION
This unit requires very little maintenance, however a Qualified Technician should inspect it at the beginning of every heating
season.
Inspection Check list:
Lighting is smooth and consistent, and the combustion fan is noise & vibration free.
The condensate freely flows from the unit, and is cleaned of sediment.
Relief Valve and air vents are not weeping.
Low water cut off is flushed (if applicable)
Examine all venting, for evidence of leaks, and vent screens are cleaned.
Check the burner plate for signs of leaking.
Verify the vent clearance as per Section 3.0
Listen for water flow noises indicating a drop in boiler water flow rate. The boiler and hydronic system may need to be flushed to
eliminate hard water scale (Use Fernox DS-40 Descaler – NTI PN: 83450).
16.1 Combustion Chamber Cleaning
Once every second year the burner (No.1 – See 17.0 Parts List) and the burner door (No.19) should be removed so the
combustion burner and chamber can be inspected for flue gas blockage. Such blockage will reduce the boiler’s capacity/firing rate
and can impact negatively on how smooth, efficiently and reliably the boiler operates. Remove debris from inside the burner using
compressed air or vacuum; if water is used ensure the burner is completely air dried upon completion. Carefully remove the
insulation (No.32) from the back of the combustion chamber and vacuum out any loose build-up. With water and a non-metallic
scrub brush, thoroughly clean the heat exchanger surfaces, including in-between the tubes (note: the flue gases must pass in-
between the tubes). Rinse with a garden hose allowing the dirty water to wash out through the condensate drain, repeat until water
runs clean. Once complete, clean the condensate trap and drain lines.
16.2 HRV/Air Handler Maintenance
Once every three months. Replace furnace filter. May be required more frequently in beginning, especially if new
constructio n.
The Matrix HRV module is relatively maintenance free but does require routine cleaning. Table 14 describes the necessary
mai ntenance.
IMPORTANT
It is imperative that you explain to the homeowner that it is their responsibility to:
• Keep the vent terminal free of snow and ice.
• Periodically check the vent terminal for debris.
