Inspection & Cleaning Procedure - Thermal Solutions EVCA SERIES Installation, Operating And Service Instructions

D. INSPECTION AND CLEANING PROCEDURES
Daily Boiler Inspection & Check
1. Inspect the area to assure proper clearance from
combustible materials, gasoline, and other flammable
vapors and liquids.
2. Observe burner color. See "Pilot and Main Flame"
instructions later in this section
3. Check flame control for proper operation and shutdown.
4. Check vent and air intake piping for any obstructions.
5. Check for any water leaks in the entire boiler assembly.
a.) For leaks in the boiler secondary Victaulic® piping:
i) Disassemble the leaking coupling
ii) Clean and lubricate the gasket. Clean all surfaces
mating to the gaskets prior to reassembly.
iii) See www.victaulic.com for specific details about
the QuickVic® style 107 couplings.
NOTICE
Victaulic brand water-based Vic-Lube shall be
®
used to lubricate all coupling and flange gaskets
prior to reassembly. Oil-based lubricants shall
not be used.
6. Check for any gas leaks.
7. Check condensate drains for any obstructions.
8. Clean any debris or trash from area.
9. Check the low draft, fan, air pressure, and damper position
interlocks, according to the manufacturer's instructions,
if so equipped.
10. Check gauges, monitors, and indicators to assure they are
functioning properly.
11. Log that the above maintenance was completed in an
appliance log. Maintain log near appliance location.
Weekly Boiler Inspection & Check
1. Check flame strength for both pilot and main flames; log.
2. Check ignitor.
3. Check operation of the flame failure detection system for
both pilot and main flame.
4. Check firing rate control for proper operation.
5. Check pilot and main fuel valves:
Open limit switch and make aural and visual inspection,
check valve position indicators and fuel meters, if provided.
6. Check the low water cutoff device and alarm according
to the manufacturer's instructions.
Monthly Safety and Operating Control Checks
1. Check proper operation of all boiler system safety and
operating controls including flame safeguard.
2. Check proper operation safety relief valve.
3 Check condition of water (pH, alkalinity, hardness).
Correct water condition as needed.
4. Check carbon monoxide level in flue products.
5. Check venting/air intake and condensate drain tubes for
obstructions.
6. Repair or replace any inoperative or damaged components.
7. Low water cutoff, float type (if so equipped):
Monthly blowoff. During the heating season, if an
external float type low water cutoff is above the boiler,
the blowoff valve should be opened once per month (use
greater frequency where conditions warrant), to flush out
the sediment chamber so the device will be free to
function properly.
8. Inspect and replace air filter as needed.
9. Check high and low gas pressure switch interlocks.
10. Log service procedure in appliance log.
Semi-Annual "Tune-Up"
1. Inspect condensate drain tubes for deterioration,
cracking, etc.
2. Inspect air intake and exhaust pipes for leaks, deterioration,
scale, etc.
3. Measure fuel input, oxygen and carbon monoxide in flue
products.
4. Adjust burner to obtain values noted in firetest report.
5. Complete safety and operating control checks.
6. Repair or replace any inoperative or damaged components.
7. Log service procedures in water appliance log.
Annual Boiler Inspection and Check
1. Replace air filter.
2. Remove and inspect pilot assembly.
3. Remove lower front jacket panel and check for any signs
of corrosion and leaks.
4. Remove pipe plugs in header and inspect inside of copper
tubes and header.
5. Flush boiler and mechanically remove any scale.
6. Remove, inspect, and clean water flow switch and low
water cutoffs.
7. Complete "tune-up" procedures (See previous instructions).
8. Log service procedures in appliance log.
9. Repair or replace any inoperative or damaged components.
10. Vent/Air Intake System. Inspect for obstructions, soot
accumulation, proper support, and deterioration of pipe,
fittings, and joints.
a.) Clean terminal screens. Terminals must be
free of obstruction, undamaged, with screens
securely in place.
b.) Terminal and wall thimbles (if used) must be
weathertight.
c.) Pipe must be full round shape, and show no
damage from impact or excessive temperature.
d.) Pipe must be supported at minimum (5) foot
intervals and must not sag.
e.) All vent joints must be secure and watertight.
f.) Horizontal vent tee drain or vertical vent tee
drain (if used) must have minimum 6 inch trap and
allow condensate to flow freely.
To clean:
i.) Disconnect drain tube from drain fitting
ii.) Flush drain tube with water. Fill trap with water.
iii) Securely fasten drain tube to drain fitting,
providing gas-tight and watertight seal.
g.) If pipe must be disassembled for removal of
obstructions or resealing of joint, see VENTING
section of the manual.
11. Low Water Cutoff (if so equipped)
a.) Float type low water cutoffs should be dismantled
annually by qualifiied personnel, to the extent necessary
to ensure freedom from obstructions and proper
functioning of the working parts.
i.) Inspect connecting lines to boiler for accumulation
of mud, scale, etc. and clean as required.
