Lynx Combi Boiler

2. CONDENSATE REMOVAL SYSTEM
Lynx boilers are equipped with a built-in condensation
drain and trap. The trap must be filled with water. DO
NOT operate the boiler without filling the trap with water
to prevent flue gas discharge into space. Periodic
inspection should be made of this assembly for deterio-
ration of the tubing and to insure that the trap is not
plugged. If it is plugged or appears to have excessive
sediment in it, it should be removed from the drain
assembly, straightened out to clear the obstruction,
reformed, filled with water and reinstalled as before.
(See Figure 7).
Leave the top of the condensate drain tee open, to act
as a vacuum breaker. Do not allow any part of the
condensate removal system to be exposed to freezing
temperatures, or any other conditions that could cause
blockage.
If a neutralizing system is installed, the filter medium will
require periodic changing, to ensure it’s effectiveness.
Refer to the neutralizing unit’s manufacturers instruc-
tions, if available, or change the medium on an annual
basis.
3. PIPING INSPECTION
Look at all water piping. There should be no leaks or
signs of leaks at any pipe joints or around the boiler.
4. SYSTEM WATER PRESSURE INSPECTION
The boiler water pressure is indicated on the pressure
gage. The boiler water outlet temperature is normally indi-
cated on the temperature display (See Figure 9 for digits
illustration). For most installations, the pressure gage
should indicate about 12 to 15 psi pressure when temper-
ature is about 70 to 100F and from 15 psi to 25 psi when
temperature is up to 195˚F. FOR YOUR SYSTEM, there is
one correct pressure for each temperature. ASK YOUR
INSTALLER OR SERVICEPERSON TO EXPLAIN AND
SHOW YOU. Learn what normal pressure to look for. If
pressure increases from normal, the relief valve will open
to relieve the pressure. Call your service organization if
pressures are higher or lower than normal, and if the relief
valve spills water. Repair or adjustment is needed.
5. UNUSUAL NOISE
Stand near the boiler and look and listen. As the burner
start and shut off, there should be no unusual noise.
6. BOILER ROOM AIR SUPPLY
Ample boiler room fresh air is required for combustion
(non-direct vent installation) and ventilation (direct-vent
installation).
Check air vents for continues positive supply of air as
required. Air needs are greatest in cold weather if boiler
installation is non-direct vent method. Air vents must be
open and free of obstruction.
Warning:
The flow of combustion and ventilating air to the
boiler should not be obstructed.
Warning:
If you find any problem during your inspection, call
for service immediately.
The combustion air supply must not be susceptible to
contaminants, which may cause corrosion or other
damage to the heat exchanger and components of the
boiler, causing failure of these parts or unsafe
operation.
Below is a list of products which must be avoided from
being stored or entering the boiler room or air supply
area:
