RE: Call for Qualified Wood Pellet Boiler Technologies for Renewable Heat NY

Dear Sir/Madam

,

Evoworld is pleased to submit an additional testing report for our P14 model in order to ensure this high performance wood pellet boiler qualif ies for the Renewable Heat NY program. The testing was done to EN303.5 by

Francisco Jos ephi num Wi e selbu rg BLT which is consistent with the requirement of an independent, third party that is technically competent to conduct the performance testing and analyze the results.

The summary table below shows that each of our models meet s the requirements. The s preadsheet for the
conversion calculations is attached.

Summary

Unit 14P 25P 50P 100P 200P

Efficiency on HHV 88 85 90 88 87 PM2.5 (Dust and VOC) lb/mmBtu 0.016 0.019 0.014 0.019 0.023

CO at 7% O2 PPM 57 212 28 74 20

Please let us know if any additional information is required. We look forward to being active participants in the

Rene wable Heat NY and other similar prog r ams.

Thank you,

Lou Okonski
President

The boiler must be installed with a surge protector or equivalent.

Wear parts: 1 year Wear parts include any part exposed to movement and/or excess heat such as, but not limited to: gear boxes, augers, auger channels, pellet tubes, combustion chamber, cleaning mechanism components, fan blades, fuel level fork, and any ot her component similarly exposed to temperatures over 150 F and/or those that move.

Painted parts: 1 year
Painted parts include any part that has a painted finish and does not fall into any of the above categories.

The warranty is immediately void under the following situations such as, but not limited to:

Failure to protect the boiler from the elements such as rain, snow, extreme heat, extreme cold, excess humidity, and liquid water; failure to protect the boiler from freezing; failure to install the near boiler mixing valve; failure to keep the return temperature above 55C (131F); use of non

- woody fuel such as but not limited to, grass, corn, manure, agricultural products, cherry pits, garbage, plastic, and petroleum products; use of
fuel other th an wood pellets certified premium (or better) without any additives by the Pellet Fuel Institute in a pellet boiler; use of any petroleum or chemical additives to the fuel; wood chips that do not meet the G30/G50 requirement per ONORM 7133; lack of use of the recommended thermal storage volume; bypassing the recommended thermal storage volume; improper venting; overpressurization of the system; failure to pressurize the system i.e. installing it as an open system; failure to have the boiler inspected and serviced

### annually by a certified service technician; failure to conduct the maintenance as outlined in the operation manual; and accessing and/or altering settings within the service menu without explicit consent from
