EcoLet™ | Through-Wall Installation Kit for the 240v Range

All Heated EcoLet™ systems must have insulated vent pipes when exposed to the outside air.

The standard EcoLet™ kits come with a through ceiling vent pipe setup and will not need this kit if this setup is chosen.

All the EcoLet™ 240v /25e/65e models must not have a bend sharper than 45 degrees, which will restrict ventilation.

Installation kit includes the following:

• Through-wall-kit assembly (black)
• One additional 50mm 45 degrees bend (Maximum number of bends is 3)

1 Meter Extensions:

• Two 1.2 Meter 100mm housing extensions (color black)
• Two lengths of exterior-rated 50mm vent pipe insulation
• A 50mm vent pipe is included in the base EcoLet™ package
• Two 100mm pipe saddles are included with two timber or brick mounting brackets to suit your mounting needs

* 2 to 3 Additional 1.2 Metre Extensions are required if the ventilation stack is more than one story high.

* Each 1.2 Metre Extension has an installed length of 1.1mm

Notes; 

Standard NZ plumbing fittings do not fit the EcoLet™ ventilation pipe.
Maximum bends - no more than 3 bends in total.
Above the roof, ventilation components are included with the EcoLet™ system package.
