A Mendota firebox leaves the factory dressed in whatever front, liner, and log set the buyer picked, and most of what owners notice going wrong lives in those choices. A bay front fogs, a log set shifts, a blower starts to rattle. Chimney Sweep Delta repairs them as separate parts and leaves the pilot, valve, and venting to the gas fireplace repair page.
Glass on these fireplaces comes in three shapes, and each needs its own care. The bay fronts on older DXV units use a centre pane and two angled side panes, so there are more corners and more gasket length to fail; fogging at a corner is usually a gasket, not dirty glass. The FV41 Arch uses a single arched pane that must seat evenly along its curved top, and an uneven seat shows as a gap at one shoulder.
The clean-face FullView models carry one large pane with very little metal around it, which makes the white film left by combustion more obvious. We clean all of them cold, with a product made for ceramic fireplace glass, and renew the gasket whenever the glass frame comes off. The barrier screen or decorative front goes back on before the next fire, since a running unit's glass can burn on contact.
Décor models add another layer, with finishes on the fronts and bases that are wiped with a soft, dry cloth rather than cleaned with anything abrasive. On every Mendota we also check the glass clips and latches, because a pane that is held unevenly cracks under heat long before its gasket wears out.
Owners across Delta bring us the same handful of appliance problems, each with a usual cause.
Fan noise that comes and goes - one of the two blowers on an FV41 working loose on its mount, or a dust-packed wheel on a single-blower unit.
Logs look flat or crowded - a Deep Timber, TimberFire, or FireIn set moved during cleaning and set back out of its pattern.
Front no longer sits square - bent mounting tabs or a missing clip on a decorative front, which also lets the louver rattle.
Louvers hot or discoloured - a blocked convection path behind the front, so heated air leaves through a smaller opening.
Liner panel cracked - a brick-pattern or decorative liner damaged by a dropped log or a tool, replaced as a panel.
Most of these are one-visit jobs once the model and front style are known. Because a Mendota is often run for hours on end through the winter, blowers and log sets wear faster than on a fireplace lit occasionally, so we check both on every visit even when the call was about something else.
One of the pleasures of these fireplaces is that the look can change long after installation. More than twenty fronts were offered, from plain to ornate, along with doors and liners, and most can be swapped on an existing firebox in an afternoon. A changed front is a good moment to clean the convection channels and inspect the glass, since the front has to come off anyway.
Some parts cross between models, which helps when a front is discontinued: fronts designed for the FV44i insert also fit the FV34 fireplace. Liners, the panels that line the firebox, come in several patterns and are sized to each model. When a decorative front is swapped we also check that the louver openings still line up with the blower outlets, because a mismatch traps heat behind the front.
An older DXV35 or DXV45 with a sound firebox, intact glass, and a burner that still flames properly is worth keeping. Blowers, gaskets, log pieces, and fronts are the usual repairs, and most remain available. A tired log set can be replaced as a set, which often makes an old unit look new again without touching the firebox.
Replacement becomes reasonable when the firebox has rusted, the glass assembly is no longer made, or repairs keep stacking up. The FV34 was designed to drop into the same framed space as the DXV35, so a swap there can avoid rebuilding the wall. We give the cost of repair and the cost of replacement side by side and leave the choice with you.
We begin with the fire off and cold. The front comes off, the glass and gasket are checked, the log set and liners are inspected, the blowers are run and listened to, and the louvers and convection channels are cleaned. Parts are quoted from the plate in the control area, and anything on the gas train is quoted separately. Each technician carries a gas licence and insurance, so a Mendota Fireplace Repair Delta visit that turns up a pilot or valve fault can continue without a second booking.
