NTI Boiler: Gas leak check before startup
Gas leak check before startup on a NTI boiler: First thing I do on any gas appliance startup is use my nose. Before and during the first start, smell at the floor and around the boiler. If there is any sign of a gas leak, do not start it. Propane is the one that fools people, because the odorant can fade in a tank or new piping and you may smell nothing even with gas present. That is why the supplier should verify the odorant level, not you guessing.
Applies to: TRX boilers on natural gas or propane
Common causes of gas leak check before startup
- Gas leak at fittings, unions or valves from install or handling
- Propane odorant level too low, so a leak goes unnoticed
- Loose connection disturbed during boiler setup
- Damaged flex connector or gas valve seal
How to fix gas leak check before startup: step by step
- Smell near the floor and around the boiler before startup, since propane sinks.
- Remove the front door and smell inside the enclosure.
- If a leak is suspected, shut the boiler down at once, leave the area and do not operate switches or flames.
- Find the leak with a bubble test and repair it before restarting.
- Only licensed gas technicians should repair gas connections.
- For propane, have the supplier confirm the odorant level before startup and periodically after.
- Recheck every joint with leak solution after the repair, then start again and recheck at full fire.
