Outdoor boiler furnaces manufacturer and factory direct sales.
The EZBoiler Stove Outdoor Furnace is made out of mild steel which will corrode if left untreated and unprotected.
The following are five basic steps to maintain your stove and extend its life:
A properly installed grounding rod system will protect people from electric shock, help safeguard expensive electronic equipment, prevent electrolysis, limit neutral-to-ground voltage and satisfy the NEC along the way. Use only a 4GA or larger wire with proper grounding clips. Grind paint away where you attach it to the stove in order to get a solid electrical connection.
Anode rods are commonly used in hot water heaters to prevent rusting of the water tank. They are designed to neutralize the corrosive electrons that develop in the water. They are also called “sacrificial anode rods” because they corrode away instead of having your water tank corrode. Anode rods work for an outdoor boiler as well. The easy way to install one on your Ezboilers stove is to add a tee fitting to the stove’s drain port, install the anode rod straight into the water jacket, then add your drain shutoff valve on the side of the tee. When you drain and flush your stove once per year, it’s a simple matter to remove the anode rod for inspection, and replace it if necessary.
The sodium nitrite treatment is specially formulated to decrease corrosive build-up. You can order it straight from the manufacturer: Corrosion Control 800 Once a year during the off season, when the EZ Boiler is not in use, drain and flush the water jacket and refill it with water and a unit of sodium nitrite. Fill the water jacket completely to the top of the vent at this time so that all surfaces of the water jacket will be covered during the off season. This will help prevent rust and corrosion from attacking the top of the water jacket during the idle off season period. If significant amounts of water need to be replenished during the heating season, add enough additional sodium nitrite to maintain protective levels.
Coals and Ash
Pull the ash and coals to the front of the firebox before loading. Be sure to get right down to the firebox metal. This will improve heat transfer to the water jacket and reduce creosote build-up which could lead to creosote corrosion. Make it your daily practice to move the sides of the ash pile where it touches the firebox as well. An undisturbed ash line would allow creosote to build up in one spot, leading to corrosion. It is the number 1 cause of firebox failure. Empty old ashes periodically as needed.
Cover the chimney to prevent rain water from getting inside the firebox. Clean out all the ashes and optionally coat the exposed metal with a light coating of oil. This will prevent the firebox from rusting in the off season.
Premature failure of a firebox is almost always caused by incorrect routine maintenance. It is absolutely vital that you avoid letting the ashes build up undisturbed, especially in the rear and the sides of the firebox. Creosote will build up on top of that ash line, and eat through the steel eventually.
It only takes minutes per week to move those ashes and scrape the firebox to prevent a build-up. Combine that with a thorough cleaning at the end of the heating season, and your stove will easily last 20 years or more.
