The gas train on these fireplaces is run by electronics, which changes what a licensed gas technician from Chimney Sweep Chilliwack does on the first visit. Meters come out before wrenches do, and the module, the sensing rod, the batteries, and the pairing are proven good before the valve or the pressure is questioned. This page covers that gas fireplace repair work; glass, panels, fans, and lighting are on the appliance repair page.
These Heat & Glo fireplaces carry a battery backup so the IntelliFire module can still light the fire when the power is out, and that one feature explains a large share of the winter calls we take. Batteries left in the tray for years leak, the contacts corrode, and the fireplace that worked all autumn on mains power will not light the night it matters. We change the backup batteries at every service and clean the tray, which is the cheapest repair on the whole unit.
Cold weather adds two more patterns. A direct-vent termination on a north wall ices over during a freeze and thaw, and the sealed firebox then runs short of air, so the pilot proves and the burner starves. Power-vented models, which use a fan in the vent run to reach a distant termination, cannot run during an outage at all. An owner in Chilliwack who expects a fire during a storm should know which vent type the house has. The first start of the season, after a summer with the gas off, is the other reliable call, because a pilot line that has sat empty needs several tries to purge.
Ignition complaints on these units sort by where in the spark-prove-open chain they fail, and each entry below names the part we test first.
Pilot lights but the main burner never follows - a sensing rod coated with deposits or bent out of the flame, so the module never proves the pilot and never opens the valve.
Runs a minute, shuts down, relights, repeats - flame rectification dropping out: a cracked ceramic insulator on the rod, a poor ground at the module, or a leaking glass gasket cooling the pilot.
Lights on batteries but not on mains power - the transformer or its plug at the module, which the batteries have been quietly covering for.
Needs several tries on cold mornings - low inlet pressure when every appliance in the house calls at once, or a pilot orifice narrowed enough to miss the spark gap.
Soft whoomp at light-off - the burner catching late because the pilot flame is small or the crossover ports are blocked by ember material.
Rotten-egg smell near the unit - stop, close the shut-off valve, open a window, and call from outside the room; this is a leak until proven otherwise.
An IntelliFire module that clicks a set number of times and then goes silent has locked out, which is the system doing its job: it refused to keep sending spark to a pilot that would not prove. The module watches the flame rectification signal from the sensing rod, a tiny current that only flows when flame bridges the rod to the burner. If that current never appears within its window, the module shuts the gas off and waits for a reset. A power cycle clears the lockout; it does not fix the cause.
On a repair visit we meter that signal directly, with the pilot burning, rather than guessing from the symptom. A weak reading with a clean rod points at the ground path or the module itself, and a reading that drops as the firebox warms points at a gasket drawing in cold air. No reading at all with a strong pilot means the rod wiring has broken. That one measurement separates a module replacement from a wiring repair, and it takes less time than opening the valve.
Parts for the gas train on a Heat & Glo depend on which IntelliFire generation the fireplace carries, and the rating plate plus the remote in your hand tell us. The original IntelliFire, IntelliFire Plus, and IntelliFire Touch each use their own module. A Touch module expects a wireless wall switch and receiver that an older unit does not have, so a mismatched module simply will not pair. Sensing rods and pilot assemblies are ordered for the fuel on the plate, natural gas or propane, and a conversion between fuels is a licensed job that ends with a pressure check at the valve.
The valve itself is the last part we suspect and the last we replace, because a valve that will not open is far more often waiting on a signal it never received. Keep the carbon monoxide alarm nearest the fireplace tested monthly, and treat any alarm during a burn as a stop-and-ventilate event. With its sensing rod cleaned yearly and the gasket kept tight, the ignition module on these units runs for many seasons without replacement.
Before calling, note whether the fireplace clicks, whether a pilot flame appears at all, and whether it behaves differently on batteries than on mains power. Those three answers tell us which part of the chain has failed before we arrive. The gas licence and insurance that Chimney Sweep Chilliwack holds cover this work, and most IntelliFire repairs finish on the first visit once the module generation is known.
