Outdoor Furnace: How To Clean Your Filter In 15 Seconds New Procedure Announcement!

How To Clean Your Filter In 15 Seconds New Procedure Announcement!

Why Boilers Need A Filter

Sediment is the "Secret Killer" of outdoor boilers. It will eat through steel, AND cause electrolysis damage to your water jacket - holes in your boiler are very bad.

Most outdoor wood burner owners already have a filter. But some dealers make the mistake of NOT recommending a filter to "get the sale". This is not wise. If you don't have a filter, this is not your fault of course if your dealer did not even tell you about it. But you still need one to protect your system. Learn more by clicking HERE.

We get calls from outdoor boiler owners whose systems are from 3 to 7 years old and who need to replace all their heat exchangers at great cost. This could have been prevented if they had a filter.

Sediment Buildup

If you don't have a filter, you can install one now easily. This will reverse the damage being caused by sediment, and clean up your system perfectly!

Filter kits are available! They include literally every component needed to install a filter, including the bypass. A bypass is required to allow the water to continue flowing while the filter is getting cleaned every month or two. Simple instructions and drawing for the filter are included with every Filter Kit.

You can now clean your filter in 15 seconds!  While you should still remove the filter cartridge and give it a good cleaning as needed, you can now flush sediment from your filter cartridge quickly and easily using this new method.

 Under normal operation, your bypass is closed, and water flows through the filter as shown in Figure 1 below.  Note that water normally flows from the outside INWARD through the filter, so any sediment trapped by the filter will collect on the OUTSIDE of the stainless steel filter cartridge.

New Procedure Explained

Utilizing the new "QUICK-FLUSH" cleaning procedure, you simply do the following:

  1. Open the bypass valve
  2. Close Valve #1
  3. Hold a bucket under the filter (to catch water and sediment flushed out)
  4. Open the red valve at the bottom of the filter (see Figure 2 below)

This procedure reverses the flow of water in the filter and forces water to flow from the inside out. Therefore, much of the sediment on the filter will flush out and flow into your bucket!

Maintaining a clean filter will extend the life of your boiler, and your heat exchangers!
