Maintenance Checklist: Burnham Boilers and Beyond (Space Heaters, Crawl Space Dehumidifiers, and Frigidaire Gallery Ice Makers)

Who This Checklist Is For

If you manage a facility with a Burnham boiler, or you're responsible for ordering Burnham boiler parts and coordinating service, you know the routine: something breaks, you scramble for a fix, and you promise yourself you'll be more proactive next time. This checklist is for you. It's based on five years of ordering parts, hiring contractors, and maintaining a multi-building property. I don't have hard data on how much this checklist actually cuts downtime, but anecdotally, it's saved me from at least three after-hours calls. It's broken into five action items. Follow them in order, and you'll go from reactive to organized.

Step 1: Lock Down Your Annual Burnham Boiler Inspection

This is the no-brainer. You've heard it a thousand times, but the bottom line is: most contractors push clients to skip this because they're afraid of losing business to a newer brand. All I'm saying is: stick with Burnham for safety margin and for warranty protection. The typical inspection covers flue gas temperatures, heat exchanger cleanliness, and a combustion analysis. Honestly, last year I found a crack in my heat exchanger during a routine inspection—caught it before it became a leak. That alone paid for the inspection fee for a decade.

Checklist for this step:

• Confirm the burner is firing cleanly (CO₂ reading between 9–10% for gas).
• Check the expansion tank pressure: should equal static system pressure (usually 12–15 psi).
• Inspect the flue for soot or condensation buildup.

I don't have hard data on what percentage of inspections find these issues, but my sense is it's about 20–30% of first-year inspections on boilers older than five years.

Step 2: Verify Burnham Boiler Parts Availability and Condition

After the inspection, you'll often need Burnham boiler parts—gaskets, pressure switches, control boards. I learned this the hard way when a broken pressure switch had my building cold for three days before I found the correct part online. Now, every year I stock a small inventory of the most likely-to-fail items. The thing is, parts availability varies dramatically by region. Some dealers keep stock for 10–15 year old models; others drop support after 8 years.

What worked for me:

• Ask your contractor for a list of the top three failure-prone parts for your model.
• Compare the part numbers against Burnham's published parts list (available on their site).
• Buy one spare of each—costs maybe $100–200 total, and it's a game-changer when a failure happens on a weekend.

Pro tip: Always check the revision number. I once ordered a control board that looked identical but had a newer revision that was incompatible with my wiring. Cost me an extra 2 hours in returns.

Step 3: Manage the Installation Environment—Especially Crawl Spaces

If your Burnham system is in a crawl space (and many indirect water heaters are installed there), a crawl space dehumidifier isn't optional. It's a red flag if your installer skips it. Moisture corrodes copper fins, rots wiring connections, and can void your warranty. I added a small dehumidifier unit to my crawl space two years ago and noticed the air quality in the basement improved noticeably—no more musty smell when the heating kicks on.

A few guidelines:

• Target humidity level: 40–60% RH. Anything above 65% is inviting corrosion.
• Most crawl space dehumidifiers pull about 5–8 amps. Make sure your outlet isn't on the same circuit as the boiler.
• Check the drain line quarterly—clogs can lead to overflow and mold.

I don't have hard data on how many boilers fail because of humidity, but I've personally replaced two circulator pumps on systems with high-moisture crawl spaces. That's not nothing.

Step 4: Assess Your Backup Heat Strategy—Space Heaters

Even the best-maintained Burnham boiler will occasionally need a repair. For those 24-hour windows, a good space heater can save your building from freezing pipes. I didn't have a smart space heater for emergencies until a power outage taught me the value of one with a thermostat and tip-over protection.

What I look for now:

• Thermostat-controlled (not just high/medium/low). That way it maintains a set temperature and doesn't run continuously.
• UL-listed and auto-shutoff for overheating.
• Capacity: for a small room, 1500W is plenty. For a large open area, get two and place them on opposite sides.

One mistake I've seen: people use space heaters as a permanent heat source instead of fixing the boiler. That's a fire risk and a waste of energy. It's a temp fix, not a solution.

Step 5: Don't Forget Kitchen Appliances—Especially the Ice Maker

I know, I know—this seems out of place in a boiler checklist. But trust me: if you're managing a facility with a commercial kitchen or a break room, the Frigidaire Gallery ice maker is something you'll get called about weekly. I don't have hard data on how quickly a dirty ice maker impacts ice quality, but anecdotally, I've noticed a huge change in taste after cleaning. The good news is that cleaning it is straightforward.

To clean a Frigidaire Gallery ice maker:

1. Turn the unit off and unplug it.
2. Remove the ice bin or scoop.
3. Pour a mixture of 1 part white vinegar to 3 parts warm water through the water reservoir.
4. Let it sit for 10 minutes. Then run a few rinse cycles with fresh water.
5. Wipe the interior with a clean cloth.

Do this quarterly. It takes about 30 minutes, and it keeps complaints down. Plus, it shows that you're on top of the details—which matters to the operations director when they walk through.

Common Mistakes and Warnings

Here are a few pitfalls I've encountered (the hard way):

• Skipping the burner phase check: Not all technicians do this. Insist on it. It's how you catch a failing ignitor early.
• Ignoring the expansion tank: If it's waterlogged (not air), it will cause pressure relief valve constant dripping. Replace it.
• Using generic parts to save $50: A $50 difference per repair today often translates to a call-back later. I learned that when a non-OEM pressure switch failed within 6 months.
• Forgetting the ice maker's water filter: If it has a filter, change it every 6 months. Hard water will clog it fast.

So that's my checklist. It's not perfect, but it's been refined over years of trying and failing. If you take one thing from this: lock down the annual inspection first, then stock the spare Burnham boiler parts you know you'll need. The rest is just details, but details matter when you're the one getting the call at 3 PM on a Friday.
